PORTION CONTAINER COMPRESSION SYSTEM

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a portion container compression system capable of pushing out a content of a portion container by compressing the same.

2. Description of Related Art

Conventionally, as such a kind of system, there have been known a liquid feeding system as disclosed in Japanese Unexamined Patent Application Publication (Translation of PCT Application) No. 2008-520298 and a liquid feeding system as disclosed in Japanese Patent No. 4485869. The liquid feeding system of Japanese Unexamined Patent Application Publication (Translation of PCT Application) No. 2008-520298 has a communicative operation mechanism established by providing a spike on a portion holder. Particularly, the spike serves to bore a hole in a portion container stowed in a concave space of the portion holder such that a housing space of a container body and a liquid-containing section are allowed to be communicated with each other through a communication hole. As for the liquid feeding system of Patent document 2, a communicative operation mechanism is established by providing on a portion holder a cutter used to break a seal lid of a mouth section of a portion container.

Since each of the conventional liquid feeding systems described above has the communicative operation mechanism established by providing on the portion holder a spike or a cutter, the structure of each system is complex, thus making it difficult to wash the system after use and possibly injuring hands due to the spike or the cutter.

In view of the aforementioned problems, there has also been known a liquid feeding system as disclosed in Japanese Unexamined Patent Application Publication No. 2012-135518. This system includes: a portion container formed by sealing a mouth section of a container body; a portion holder having a concave space capable of stowing the portion container; and a communicative operation mechanism established by forming on a bottom section of the concave space of the portion holder a communication hole for communicating the concave space with a liquid-containing section provided therebelow. That is, a housing space of the system main body and the liquid-containing section are communicated with each other through the communication hole. Particularly, the communicative operation mechanism is configured as follows. That is, there is also provided a compression mechanism capable of compressing the portion container stowed in the concave space. Here, in accordance with the way the portion container is compressed by the compression mechanism, formed on this portion container is a peeling induction portion allowing a content to leak out as the seal lid is partially peeled from the container body. Specifically, with the portion container being stowed in the concave space, the peeling induction portion is positioned at a region of the bottom section and faces the communication hole.

SUMMARY OF THE INVENTION

The problem with the portion container disclosed in the aforementioned patent document is that since the shape thereof is that of an oval and is symmetrical in the front-back direction, the portion container may be erroneously installed in the system such that the content may be ejected when the orientation of the peeling induction portion is not properly adjusted. Especially, an oval-shaped object is more likely to be misaligned in the front-back direction. Further, when squeezed in an improper manner, the content may be spattered on surrounding items from the portion container such that clothes or the like may be contaminated.

In view of the aforementioned problem, it is an object of the present invention to provide a portion container compression system capable of preventing a portion container from being misaligned, and being safely used without contaminating surrounding items even when the portion container has been misaligned

The invention of a first aspect is a portion container compression system capable of squeezing a portion container aligned to a receiving portion of a system main body and pushing out a content of the portion container. The system includes: the receiving portion for installing the portion container; and the portion container, in which the receiving portion includes a misalignment-prevention portion allowing a front region of the portion container to be aligned to the receiving portion while preventing a back region of the portion container from being aligned to the receiving portion, and in which the portion container is formed into an asymmetric shape in a front-back direction and includes an easily unsealable portion formed on the front region thereof.

According to the portion container compression system of a second aspect, the misalignment-prevention portion allows the front region of the portion container to be positioned to the receiving portion with the easily unsealable portion being positioned downward; and allows a misalignment of the portion container to be recognized when the back region of the portion container is positioned to the receiving portion, since an area of contact between the back region of the portion container and the receiving portion is smaller than an area of contact between the front region of the portion container and the receiving portion.

According to the portion container compression system of a third aspect, the receiving portion further includes at least one receiving claw portions formed on a left and right regions thereof, and the misalignment-prevention portion is provided in a center of the receiving portion, the receiving claw portions and misalignment-prevention portion allowing the front region of the portion container to be positioned under the misalignment-prevention portion when the portion container is positioned to the receiving claw portions.

According to the portion container compression system of a fourth aspect, the misalignment-prevention portion abuts against a side surface of the portion container when the back region of the portion container is positioned to the receiving portion.

The invention of a fifth aspect is a portion container compression system capable of, by swinging a handle, squeezing a portion container aligned to a receiving portion of a system main body and pushing out a content of the portion container. The system includes: the receiving portion for installing the portion container; and the portion container, in which the receiving portion is disposed away from a center and toward the handle, and causes a misaligned portion container to fall in a region opposite to the handle upon swinging the handle, and in which the portion container includes an easily unsealable portion formed on a front region thereof.

According to the portion container compression system of a sixth aspect, the receiving portion further includes: at least one receiving claw portions formed on a left and right regions of the receiving portion; and a misalignment-prevention portion provided in a center of the receiving portion, the receiving claw portions and the misalignment-prevention portion allowing a part of the portion container to be positioned under the misalignment-prevention portion when the portion container is positioned to the receiving claw portions.

According to the portion container compression system of a seventh aspect, the portion container has a substantially flat bottom surface portion, and is aligned to the receiving portion with the bottom surface portion slanting toward the handle.

According to the portion container compression system of an eighth aspect, the system main body can be used as a mouth for drinking and a plug body, and a beverage can be consumed from a hole provided in a region opposite to the handle.

According to the invention of the first aspect, the misalignment-prevention portion makes it impossible for the portion container to be positioned back to front such that the misalignment of the portion container can be prevented. Further, according to the first aspect of the present invention, the front region of the portion container is obliquely positioned downward to the receiving portion, thus also making it possible to prevent the portion container from being misaligned.

According to the invention of the second aspect, since the area of contact between the back region of the portion container and the receiving portion is smaller than the area of contact between the front region of the portion container and the receiving portion, the user is allowed to recognize the misalignment of the portion container.

According to the third aspect of the present invention, since the left and right receiving claw portions and the misalignment-prevention portion serve to hold the front region of the portion container, it is now difficult for the portion container to rise even when compressed from above.

According to the fourth aspect, the misalignment-prevention portion abuts against the side surface of the portion container such that the area of contact between the portion container and the receiving portion can be small

According to the invention of the fifth aspect, a misaligned portion container falls in the region opposite to the handle upon swinging the corresponding handle, thereby making it impossible or difficult to compress this portion container, thus allowing the user to easily notice the misalignment of the portion container.

According to the invention of the sixth aspect, since the left and right receiving claw portions and the misalignment-prevention portion serve to hold a part of the portion container, it is now difficult for the portion container to rise even when compressed from above.

According to the seventh aspect of the present invention, the portion container is obliquely aligned to the receiving portion, and the slanted and substantially flat bottom surface portion is squeezed by swinging the handle, thereby making it easy to squeeze the portion container and also making it possible to prevent the portion container from being misaligned. Further, according to the seventh aspect, the obliquely aligned portion container easily falls in when misaligned.

According to the eighth aspect of the present invention, the hole can be used as a flow passage, and therefore the system can be used as a beverage container.

DETAILED DESCRIPTION OF THE INVENTION

Preferred embodiments of the present invention are described with reference to the accompanying drawings. However, the embodiments described hereunder shall not limit the contents of the present invention that are described in Claims. Further, not all elements introduced hereunder are necessarily the essential elements of the present invention.

First Embodiment

With reference to FIG. 1 to FIG. 17, described is a first embodiment where the present invention is applied to a portion container compression system. The portion container compression system 1 can be disposed on or attached to a metal bottomed container 2 of a handheld size. In this embodiment, the portion container compression system 1 is detachably attached to an upper opening section 3 of the container 2.

The container 2 has a heat-insulating double-layered structure where an inner cylinder 5 and an outer cylinder 4 are coupled to each other by integrally joining together the edges thereof in the upper opening section 3, and where a space between the outer cylinder 5 and the inner cylinder 4 is formed as a vacuum heat-insulating layer 6. Here, formed on the upper inner circumference of the outer cylinder 4 is a first female screw portion 7 allowing the portion container compression system 1 (referred to as compression system hereunder) to be screwed thereto. The compression system 1 serves to compress a portion container 8.

The compression system 1 includes: a mouth body 10 serving as a system main body that is made of a synthetic resin; a ring portion 11 fitted onto the mouth body 10; a shoulder member 12 that is provided below the ring portion 11 and is externally attached to the upper opening section 3 of the container 2; and a handle 13 pivotally attached to one end of the shoulder member 12 all of which are made of a synthetic resin.

The mouth body 10 is made of a synthetic resin, and is integrally formed of an upper protruding wall 14 and a lower cylindrical portion 16. The upper protruding wall 14 has a cylindrical shape, and is attached above the upper opening section 3 in a manner coaxial to the central axis thereof. The lower cylindrical portion 16 is disposed below the upper protruding wall 14 in a fashion such that the lower cylindrical portion 16 is continuously connected to the upper protruding wall 14 through a taper cylindrical portion 15 whose diameter shrinks downward. Particularly, formed inside the mouth body 10 is a communication passage 17 that is parallel to the aforementioned central axis and serves to communicate the inner and outer regions with each other. That is, the communication passage 17 is defined by the inner walls of the upper protruding wall 14, the taper cylindrical portion 15 and the lower cylindrical portion 16. The communication passage 17 communicates an outer region and an inner region of the container 2 with each other. An upper end of the upper protruding wall 14 is formed as a mouth portion 14A, and the left and right sections of this mouth portion 14A are suitable for use in drinking.

Further, provided on the outer circumference of the lower cylindrical portion 16 is a first male screw 18 engageable with the first female screw portion 7. Further, a mouth body-side water stop member 19 made of, for example, a rubber seal is provided on the lower end circumference of the lower cylindrical portion 16. Here, a cross-sectional surface of the mouth body-side water stop member 19 is substantially formed into a “U” shape. Further, the mouth body-side water stop member 19 itself is formed into an annular shape whose center is located on the aforementioned central axis. The mouth body-side water stop member 19 is fitted onto a mouth body-side attachment portion 20 that is annularly disposed on the lower end circumference of the lower cylindrical portion 16 and has a center also located on the aforementioned central axis. In the meantime, the outer circumference of the mouth body-side water stop member 19 is configured to be able to abut against a small-diameter portion 3A formed in the lower region of the upper opening section 3.

The shoulder member 12 includes a cover portion 21 capable of abutting against the upper region of the upper opening section 3; and a cylindrical portion 22 vertically extending downward from the cover portion 21. In fact, the shoulder member 12 is formed independently from the mouth body 10. Further, an annular engagement protrusion 23 is provided on the inner surface of the cylindrical portion 22, and an annular engagement concave portion 24 is provided on the outer circumference of the upper opening section 3. That is, the shoulder member 12 is to be attached to the upper opening section 3 in a fixed manner by engaging the engagement protrusion 23 with the engagement concave portion 24. The engagement concave portion 24 is formed on the outer circumference of the outer cylinder 4.

Further, an inward annular engagement protrusion 26 is provided on the upper section of the ring portion 11, and an annular engagement concave portion 27 is provided on the outer circumference of the upper protruding wall 14. The ring portion 11 is to be attached to the lower portion of the upper protruding wall 14 in a fixed manner by engaging the engagement protrusion 26 with the engagement concave portion 27. In this attachment state, the ring portion 11 covers the upper portion of the shoulder member 12, and a clearance 25 is formed between the upper opening section 3 and the inner surface of the ring portion 11.

An attachment receiving portion 31 for handle is provided on one end of the outer circumference of the shoulder member 12. This attachment receiving portion 31 includes: a pair of left and right attachment arm portions 32, 32 protruding obliquely upward; and a left and right engagement arm portions 33, 33 that protrude outward and are continuously connected to the lower sections of the attachment arm portions 32, 32. As shown in FIG. 2, a substantial “L” shape is formed due to the fact that the attachment arm portions 32 and the engagement arm portions 33 are continuously joined together. Further, the engagement arm portions 33 are so formed that the front end sections thereof point obliquely downward. In addition, a rotation center shaft 34 of the handle 13 is provided between the pair of left and right attachment arm portions 32, 32, and the center of this rotation center shaft 34 is located above the upper opening section 3.

The handle 13 integrally includes: an attachment portion 35 to be disposed between the left and right attachment receiving portions 31, 31; and a substantially L-shaped handle body 36 provided on the front end of the attachment portion 35. Specifically, the attachment portion 35 is pivotally joined to the attachment arm portions 32 through the rotation center shaft 34. In fact, the attachment portion 35 of the handle 13 is integrally provided on the handle body 36 in a manner such that the attachment portion 35 is particularly disposed in a direction opposite to the direction along which the handle body 36 is bended.

Further, the handle body 36 includes: a handle base portion 36K that is engageable with the engagement arm portions 33; a handle front end portion 36S extending downward from the front end of the handle base portion 36K; and a bended portion 36C provided between the handle base portion 36K and the handle front end portion 36S. Furthermore, a left and right concave side walls 37, 37 are formed, in a left-right width direction, on both sides of the handle attachment portion 35 and the handle base portion 36K, the left and right concave side walls 37, 37 substantially corresponding to the width of the attachment receiving portion 31. That is, as for the handle 13, the left-right width of the section where the concave side walls 37, 37 are formed is smaller than other sections, and the attachment arm portions 32 and the handle base portion 36K are disposed between the left and right attachment receiving portions 31, 31.

At an initial position also referred to as a fixed usage position, the handle front end portion 36S points downward, and handle boundary portions 38 each having a clearance are formed at front ends 33S of the engagement arm portions 33. Due to a locking member 41 of a locking mechanism 40 for fixing the handle 13 at the initial position, a given clearance can be secured at the handle boundary portions 38 when locked. Further, as shown in FIG. 9, the handle boundary portions 38 are formed on the front end regions of the concave side walls 37.

The locking mechanism 40 includes a downward protrusion 42 that is disposed on the outer circumference of the shoulder member 12 and serves as a locking engagement portion. Specifically, this downward protrusion 42 is provided below the attachment receiving portion 31. More specifically, a transverse part 39 is so provided on the outer circumference of the shoulder member 12 that the transverse part 39 protrudes substantially horizontally. Here, a pair of downward protrusions 42 are provided on the lower portion of the front end region of the transverse part 39 in a manner such that a clearance is formed between the downward protrusions 42 in the left-right direction. Further, a concave portion 43 whose base end region and lower portion are both opened, is formed in an area ranging from the handle base portion 36K to the upper portion of the handle front end portion 36S. Disposed in this concave portion 43 is the locking member 41 integrally including: a substantially cylinder-shaped shaft insertion portion 45 for an attachment shaft 44 to be inserted therethrough; and a substantially bow-shaped curved portion 46 that is convex upward. Particularly, the shaft insertion portion 45 is substantially provided above a central region of the curved portion 46 in the longitudinal direction, and a through hole 47 serving as an engagement receiving portion is bored in the base end region (a region close to the mouth body 10) of the curved portion 46. More particularly, the downward protrusions 42 can engage with or disengage from this through hole 47. Each downward protrusion 42 is formed into the shape of a board extending in the left-right direction. There, the attachment shaft 44 is to be loosely inserted through the shaft insertion portion 45 such that the attachment shaft 44 can be attached to the handle 13 on both sides of the concave portion 43. In this way, the locking member 41 is allowed to be pivotally disposed in the concave portion 43 of the handle 13 around the attachment shaft 44. As for the concave portion 43, only the lower portion thereof is opened, whereas a front-back and a left-right regions thereof are sealed. Further, the under surface of the curved portion 46 is formed into a curved shape conforming with the under surface of the handle 13.

In addition, the locking mechanism 40 includes a biasing unit 48 for rotationally biasing the locking member 41. This biasing unit 48 is a torsion coil spring fitted onto the shaft insertion portion 45, and serves to bias the locking member 41 in a direction allowing the downward protrusions 42 to engage with the through hole 47. Specifically, end portions 48A, 48B of the biasing unit 48 serve to bias the concave portion 43 and a rear surface 46U of the locking member 41 such that an engaged state can be maintained. Moreover, the concave portion 43 is provided with an abutment receiving portion 49 allowing the front end of the curved portion 46 to abut thereagainst when swinging the locking member 41. Here, the front end upper portion of the curved portion 46 is formed as a front end-region abutting portion 50. Moreover, the front end region of the curved portion 46 is formed as a control portion 46S of the locking member 41. This control portion 46S is provided with a plurality of protrusions 46D that are aligned in the left-right direction. Particularly, the end portion 48A of the biasing unit 48 can engage with the rear surface 46U of the front end region of the control portion 46S. Further, a cover portion 46K that is curved upward is integrally provided on the base end region of the curved portion 46. This cover portion 46K has an arc-like shape centering around the attachment shaft 44, and serves to hide the biasing unit 48 by covering the same. For this reason, as shown in FIG. 7 or other drawings, the biasing unit 48 is hardly visible due to the cover portion 46K when, for example, swinging the handle 13.

Further, slanted portions 42A serving as guiding portions are partially formed on the edges of the outer regions of the downward protrusions 42. These slanted portions 42A allow an end portion 46T of the base end region of the curved portion 46 to engage therewith. This base end-region end portion 46T is substantially formed into a curved shape that has already been chamfered. Specifically, as a result of swinging the handle 13 of an unlocked state toward the initial position, the base end-region end portion 46T will abut against and engage with the slanted portions 42 such that the locking member 41 will then swing against the bias of the biasing unit 48, thereby allowing the through hole 47 to be clamped on the downward protrusions 42 due to the bias of the biasing unit 48 after the base end-region end portion 46T has passed under the downward protrusions 42. Here, the slanted portions 42A are slanted inward (toward the mouth body 10) from top down. Further, vertical edge portions 42B are formed inside the downward protrusions 42. Furthermore, as shown in FIG. 4 or other drawings, an outer edge portion 47A of the through hole 47 is slanted along the slanted portions 42A, and an inner edge portion 47B of the through hole 47 is formed along the vertical edge portions 42B in the vertical direction.

Particularly, as shown in FIG. 1, a locked state of the handle 13 refers to a state where the downward protrusions 42 are engaged with the through hole 47. There, as a result of pushing the control portion 46S upward, the locking member 41 will rotate toward an unlocked direction against the bias of the biasing unit 48 such that the handle 13 will then be turned into the unlocked state before the front end-region abutting portion 50 of the curved portion 46 abuts against the abutment receiving portion 49, thus allowing the handle 13 to be swung upward. Meanwhile, as shown in FIG. 5, in a state where the locking member 41 is not being operated, a base end-region upper surface 46J of the curved portion 46 abuts against a left and right lower edges 36G, 36G of the handle base portion 36K due to the biasing unit 48, thus allowing the locking member 41 to be positioned. Here, as a result of swinging the handle 13 downward from such positioned state, the base end-region end portion 46T of the curved portion 46 will be guided by the slanted portions 42A such that the through hole 47 will then be clamped on the downward protrusions 42, thereby allowing the handle 13 to be positioned and fixed at the initial position.

In such case, as shown in FIG. 3 and FIG. 4 or other drawings, provided on the transverse part 39 is an elastic member 57 that is composed of a rubber packing or the like and serves to bias the handle. This elastic member 57 integrally includes: a base portion 57A sandwiched and fixed between the upper surface of the transverse part 39 and the lower edge of the shoulder member 12; and an abutment portion 57B formed as a convexly curved surface. There, a clearance is provided between the abutment portion 57B and the base portion 57A for the purpose of allowing the abutment portion 57B to deform. Specifically, when the handle 13 is in the locked state, the abutment portion 57B is abutted against by the inner surface of a bended portion 35C located between the handle attachment portion 35 and the handle body 36. Here, as shown in FIG. 3 or other drawings, the abutment portion 57 undergoes an elastic deformation such that the handle 13 can be pivotally biased upward due to an elastic restorability of the abutment portion 57, as indicated by an arrow marked as “Y” in FIG. 4. In this way, the handle 13 is prevented from swinging downward such that the engaged state of the locking member 41 and the downward protrusions 42 is maintained. Further, the vertical edge portions 42B of the downward protrusions 42 abut against the inner edge portion 47B of the through hole 47 at this engaged state.

As shown in FIG. 1 and FIG. 2, at the initial position of the handle 13, the under surface of the curved portion 46 is formed into such a curved shape that it is continuous with the under surface of the handle front end portion 36S.

Disposed inside the mouth body 10 is a receiving portion 51 allowing the portion container 8 to be detachably attached thereto. In fact, the portion container 8 is to be obliquely mounted on the upper portion of the receiving portion 51. Further, the receiving portion 51 is positioned below the rotation center shaft 34. Furthermore, the receiving portion 51 is disposed in a region inside the mouth body 10 that is close to the handle 13, and a transverse protruding portion 52 is provided on and protrudes inward from one end of the inner surface of the lower cylindrical portion 16. The area of this protruding portion 52 is about a half of a cross-sectional area of the inner circumference of the lower cylindrical portion 16. An inner edge 52F of this protruding portion 52 is concavely formed outward, and is located away from the center of the mouth body 10 in the outward direction. The protruding portion 52 is configured as a receiving board.

Further, a central holding claw 53 is provided on a central region of the protruding portion 52 in the left-right direction. Furthermore, receiving claw portions 54, 54 protruding toward the central region of the mouth body 10 are formed on the left and right sides of the central holding claw 53 in a manner such that the central holding claw 53 is positioned between the receiving claw portions 54, 54. Here, each receiving claw portion 54 is slanted upward from a region close to the handle 13 toward the central region of the mouth body 10. Particularly, an upper surface 54J of each receiving claw portion 54 is formed at an angle of 20 to 70 degrees, preferably 50 degrees with respect to the horizontal plane. More particularly, the front end of each receiving claw portion 54 is formed into a curved shape. In fact, the aforementioned angle is determined such that a virtual extended line of the upper surface 54J may intersect with the inner circumferential surface of the inner cylinder 5. That is, an angle of not smaller than 20 degrees allows a content to be ejected into the container 2 without strongly hitting the lower cylindrical portion 16. Moreover, an angle of smaller than 70 degrees is preferable due to the fact that an angle of larger than 70 degrees causes the portion container 8 to be squeezed with the handle front end portion 36S standing, though depending on the shape of the portion container 8. Since the portion container 8 can be squeezed with the handle front end portion 36S standing, the portion container 8 is allowed to be squeezed from an oblique direction.

The central holding claw 53 has: an under surface 53K that is distant from and substantially parallel to the upper surface 54J of each receiving claw portion 54; and a holding portion 55 capable of holding a section of the portion container 8 that is close to a vertical groove portion 69 such that the portion container 8 does not rise when squeezed. This holding portion 55 is formed upward, and a lower end 55K thereof is formed into a sharp-pointed shape. Further, a step portion 56 is formed between the base end of the upper surface 54J of each receiving claw portion 54 and the protruding portion 52. Specifically, the central holding claw 53 serves as a protruding misalignment-prevention portion, and the front end thereof is cable of entering and engaging with the vertical groove portion 69 of the portion container 8. More specifically, a mouth hole 58 is provided between the lower cylindrical portion 16 of the mouth body 10 and the receiving portion 51. This mouth hole 58 composes a part of the communication passage 17.

An example of the portion container 8 is described hereunder. As for this portion container 8, a flange portion 62 is circumferentially provided on the opening section of a container body 61 made of a synthetic resin. Further, a seal lid 63 formed of a resin sheet such as an aluminum laminate film is adhered to the flat upper surface of the flange portion 62 through thermal welding or the like. Here, a container space 64 is formed inside the container body 61. Further, the container body 61 is formed into an accordion and cylindrical shape, and is thus capable of freely expanding and contracting in the vertical direction. Furthermore, formed on the forward region of the portion container 8 is a peeling induction portion 65 serving as an easily unsealable portion that allows the content to leak out as a result of peeling a part of the seal lid 63 off the container body 61 when using the handle 13 to compress the portion container 8. Particularly, the portion container 8 is formed into an asymmetric shape in the front-back direction. More particularly, the flange portion 62 of the portion container 8 of the present embodiment is formed into a symmetric shape in the left-right direction.

The container body 61 is so formed that it is smaller toward a bottom surface portion 66 from the opening section thereof. In addition, since a step portion 67 is also provided on the container body 61, the section of the container body 61 that is below the step portion 67 is formed smaller than that above the step portion 67. In fact, this step portion 67 allows the container body 61 to be formed into an accordion and cylindrical shape. The bottom surface portion 66 is formed as a flat surface, and may have either a round shape or a square shape. Moreover, the bottom surface portion 66 is formed at a slight angle with respect to the flange portion 62. Specifically, this angle is preferably not larger than 15 degrees from the perspective of the volume efficiency of the portion container 8.

Further, as shown in FIG. 14A to FIG. 14E, the portion container 8 has a sharp-pointed protrusion 68 that is formed on the side surface of the container body 61 and protrudes inward. That is, the aforementioned peeling induction portion 65 is configured in a manner such that a part of the seal lid 63 is to be peeled from the sharp-pointed protrusion 68 when subjected to a force pushing and opening the seal lid 63 outward. This force is applied when using the handle 13 to contract the container body 61 such that the inner pressure thereof increases. Further, since the sharp-pointed protrusion 68 protrudes inward, the vertical groove portion 69 concaved inward is vertically formed on the outer surface of the sharp-pointed protrusion 68. In this way, regions of the container body 61 that are located on both sides of the vertical groove portion 69 protrude outward. Specifically, the vertical groove portion 69 serves as an engagement portion for the portion container 8.

Further, provided on the mouth portion 14A of the mouth body 10 is a cutout section 70 corresponding to the handle 13. This cutout section 70 includes: a body-side cutout section 70A formed by cutting out a part of the upper protruding wall 14; and a ring portion-side cutout section 70B formed by cutting out a part of the ring portion 11. This ring portion-side cutout section 70B is formed into the shape of a concave portion obtained by concaving the upper edge of the ring portion 11 and the outer circumference thereof. The width of this cutout section 70 is formed larger than that of the handle 13. As shown in FIG. 7, the cutout section 70 allows the handle 13 to be rotated to a position of proximity where the handle front end portion 36S is positioned in the vicinity of the upper end of the other side of the upper protruding wall 14. Also at such position of proximity, the bended portion 36C is positioned in the vicinity of the bottom portion of the cutout section 70.

In this way, as a result of rotating the handle 13 upward, the portion container 8 placed in the receiving portion 51 will be compressed by an upper surface 36J of the handle base portion 36K of the handle 13. Particularly, this upper surface 36J is formed as a curved compression surface. Here, a clearance is formed between the upper surface 36J and the central holding claw 53 at a position where the handle base portion 36K abuts against the upper end of the upper protruding wall 14.

As shown in FIG. 1, a lid body 71 with a water stop function is detachably disposed on the upper portion of the mouth body 10. This lid body 71 integrally includes a lid upper portion 72 and a lid lower portion 73 that are made of a synthetic resin.

The lid upper portion 72 is configured as a cylindrical body sealed by a top panel. Specifically, this lid upper portion 72 serves to close the communication passage 17 when inserted into the mouth body 10, and integrally includes: a top panel 74; and an outer circumferential portion 75 extending downward from the circumference of the top panel 74.

Further, the lid lower portion 73 includes: a horizontally outward flange portion 77 formed on the upper end of a cylindrical portion 76; a lid inner sealing panel 78 that is disposed in the upper region inside the cylindrical portion 76 and serves to seal the cylindrical portion 76; and a lid body-side water stop member 79 that is provided on the lower end circumferential surface of the cylindrical portion 76 and composed of a rubber packing or the like. Particularly, the lid body-side water stop member 79 serves as an elastic water stop member for lid body, and has a cross-sectional surface substantially formed into the shape of “C.” More particularly, this lid body-side water stop member 79 is formed into an annular shape centering around the central axis; and is engaged with a lid body-side attachment portion 80 that serves as an attachment portion for attaching an elastic water stop member for lid body and is formed, as an annular member centering around the central axis, on the lower end circumferential surface of the lid lower portion 73. In addition, the outer circumference of the lid body-side water stop member 79 is configured to be able to abut against the inner circumferential surface of the lower cylindrical portion 16 of the mouth body 10.

As shown in FIG. 13, the lid body-side water stop member 79 has a cross-sectional surface substantially formed into the shape of “C.” Here, an inner circumferential concave portion 79A of the lid body-side water stop member 79 is tightly fitted onto and positioned to the lid body-side attachment portion 80, thus avoiding being unexpectedly removed therefrom. Further, vertically formed on the outer circumferential surface of the lid body-side water stop member 79 are curved protrusions 79B, 79B capable of tightly abutting against the lower cylindrical portion 16. Furthermore, each curved protrusion 79B of the lid body-side water stop member 79 has a cross-sectional surface that is formed into the shape of a tongue. Specifically, when engaged with the inner circumferential surface of the lower cylindrical portion 16 of the mouth body 10, the curved protrusions 79B are pressed against such inner circumferential surface in a manner such that the curved protrusions 79B are deformed upward.

Likewise, the aforementioned mouth body-side water stop member 19 has the same structure as the lid body-side water stop member 79. That is, an inner circumferential concave portion 19A thereof is tightly fitted onto and positioned to the mouth body-side attachment portion 20, thus avoiding being unexpectedly removed therefrom. Further, vertically formed on the outer circumferential surface of the mouth body-side water stop member 19 are curved protrusions 19B, 19B capable of tightly abutting against the small-diameter portion 3A.

The flange portion 77 is fixed to the under surface of the top panel 74 through, for example, ultrasonic welding, an adhesive agent or forcible fitting such that the lid upper portion 72 and the lid lower portion 73 can be integrally coupled to each other. Further, a second male screw portion 81 is provided on the outer surface of the upper protruding wall 14, and formed on the inner surface of the outer circumferential portion 75 of the lid body 71 is a second female screw portion 82 allowing the second male screw portion 81 to engage therewith. The engagement of these male screw portion 81 and female screw portion 82 allows the lid body 71 to be detachably installed in the mouth body 10.

The method for using the compression system 1 is described hereunder. After removing the lid body 71, the portion container 8 is to be placed by positioning the container body 61 thereof in the receiving portion 51. With the portion container 8 being placed in such manner, the peeling induction portion 65 faces the communication passage 17 (FIG. 8). That is, in such configured state, the peeling induction portion 65 is located between the receiving claw portions 54, 54, and a lower space 83 is formed below the peeling induction portion 65. Particularly, this lower space 83 is defined by the inner space of the container 2 and a section of the lower cylindrical portion 16 that is below the receiving portion 51.

Further, as shown in FIG. 8, in the aforementioned configured state, a virtual extended line 101 of the upper surface of the flange portion 62 obliquely stretches downward, and reaches toward the inner circumferential surface of the inner cylinder 5 by passing beyond the lid body-side water stop member 79. Furthermore, a splashing space 102 for the content to be ejected therein is formed beyond (obliquely downward) the easily unsealable portion along the extended line 101. Here, the upper surface of the flange portion 62 is also a surface of a bottom section of the portion container 8 in the configured state. Moreover, the flange portion 62 is arranged at the same angle as the upper surface 54J of each receiving claw portion 54.

In addition, as shown in FIG. 8, with the portion container 8 facing downward, one end (front end) of the flange portion 62 of the portion container 8 is mounted on the upper surfaces 54J of the left and right receiving claw portions 54, 54, and the central region of the flange portion 62 in the left-right direction is to be inserted as well as positioned under the under surface 53K of the central holding claw 53. There, the other end of the flange portion 62 (left end in FIG. 8) is either in contact with the inner surface of the upper protruding wall 14 or positioned in the vicinity thereof. Under this circumstance, the other end of the flange portion 62 is actually positioned below the upper end of the upper protruding wall 14 in the upper end region thereof. Further, in the configured state, the easily unsealable portion of the portion container 8 is positioned between the left and right receiving claw portions 54, 54 that are distant from each other. Moreover, a region of the upper protruding wall 14 that is opposite to where the handle is provided, is formed as a rear wall 14K located on the rear side of the receiving portion 51.

As shown in FIG. 9 and FIG. 12, for example, formed on such rear wall 14K is a bulging portion 14B for receiving the upper surface of the flange portion 62. This bulging portion 14B includes a placement surface 14S on which the upper surface of the flange portion 62 is to be placed in the configured state. This placement surface 14S slants in the same direction as the upper surface 54J of each receiving claw portion 54; and has a dimension not larger than ½, but preferably not smaller than ⅓ of the inner circumference of the upper protruding wall 14. Further, both ends 14T of the bulging portion 14B are sharp-pointed. Furthermore, in the region of the rear wall 14K, the placement surface 14S serves to support the edge section of the upper surface of the flange portion 62 in the configured state.

In this way, with the portion container 8 being positioned in the receiving portion 51, the holding portion 55 engages with the vertical groove portion 69 formed in the central region of the container body 61 in the left-right direction; the front end of the flange portion 62 is held by the receiving claw portions 54 on both the left and right sides; and the rear end of the flange portion 62 is placed on and supported by the placement surface 14S. For these reasons, the portion container 8 can be stably supported.

Meanwhile, as shown in FIG. 15, if the portion container 8 is positioned in such a fashion that it substantially horizontally rests on the central holding claw 53, the angle at which the handle 13 comes into contact with the portion container 8 differs from above even though the front and rear directions of the portion container 8 remains appropriate. In such case, the handle 13 is caused to push out the portion container 8, and is therefore incapable of squeezing the same. Further, even if the handle 13 succeeds in pressing the portion container 8, the portion container 8 cannot be unsealed when squeezed insufficiently or falling in the communication passage 17, thus making it impossible for the content to be ejected. Further, as shown in FIG. 16, the portion container 8 cannot be disposed in the receiving portion 51 when positioned laterally. Here, in FIG. 16, the front and rear sections of the portion container 8 have been turned sideways by 90 degrees in a plane view. However, the portion container 8 still cannot be aligned to the receiving portion 51 when not positioned properly in the front-rear direction even by an angle other than 90 degrees.

In this way, a user is able to recognize the misalignment of the portion container 8 whenever the portion container 8 has been misaligned horizontally or laterally, for example. That is, not only the erroneous usage of the system can be prevented, but since the portion container 8 is not squeezed in such case, clothes or other surrounding items can be prevented from being contaminated as a result of unintentionally squeezing the portion container 8. Here, the falling of the portion container 8 does not refer to the phenomenon where the portion container 8 falls entirely, but refers to a phenomenon where the portion container 8 moves down to a level incapable of being squeezed. Further, as shown in FIG. 17, even when the flange portion 62 of the portion container 8 is positioned under the left and right receiving claw portions 54, the direction of ejection even upon successfully squeezing the portion container 8 remains the same as that of the normal condition, thus preventing the content from being ejected toward the outside. In such case, since the portion container 8 is relatively positioned in the lower region, the handle 13 cannot serve to sufficiently squeeze the portion, thereby making it impossible for the user to achieve his/her primary objective of squeezing the portion container 8, thus allowing the same user to notice that the portion container 8 has been misaligned.

Meanwhile, when positioning the portion container 8 to the receiving portion 51 and the rear wall 14K back to front, the central holding claw 53 abuts against the side surface of the container body 61, and the flange portion 62 cannot sufficiently engage with the receiving portion 51. Particularly, the area of contact between the flat upper surface of the flange portion 62 with the peeling induction portion 65 positioned downward and the upper surfaces 54J, 54J of the left and right receiving claw portions 54, 54, is smaller than that of FIG. 8 in which the portion container 8 is installed correctly. There, the portion container 8 will be disengaged from the left and right receiving claw portions 54 once the handle 13 has come into contact with the portion container 8. The portion container 8 will then either fall in the communication passage 17 or become hardly squeezable, thus avoiding being squeezed when installed improperly. This occurs due to the fact that the central holding claw 53 may not be sufficiently inserted into the vertical groove portion 69, or, for example, the fact that the portion container 8 may fail to be symmetrically aligned in the front-rear direction due to the restrictions imposed by the shape of the portion container 8.

Next, the user unlocks the handle 13 by manipulating the locking member 41 such that the handle 13 is allowed to be swung upward. There, as shown in FIG. 8, the upper surface 36J of the handle 13 will come into contact with the bottom surface portion 66 of the portion container 8 once the handle front end portion 36S has become substantially perpendicular. At that time, by applying a force to rotate the handle front end portion 36S downward, the bottom surface portion 66 will be pressurized and squeezed substantially in parallel with the flange portion 62. For this reason, a pressure inside the container body 61 increases, thereby causing the seal lid 63 around the peeling induction portion 65 to be removed from the container body 61, thus allowing the content to be obliquely ejected downward. Particularly, the direction by which the content is ejected is either substantially along the extended line of the flange portion 62 or slightly therebelow.

In such case, the handle 13 swings around the rotation center shaft 34. Specifically, the user manipulates the handle front end portion 36S such that the portion container 8 can be pressed by the upper surface 36J that is located closer to the rotation center shaft 34 than a manipulation point. That is, the content is allowed to be pushed out with a small force by applying the principle of leverage. Further, a force is easily applied since the container body 61 is pressed by the action of pushing the handle front end portion 36S downward.

In this way, for example, a hot water can be contained in the container 2, and the portion container 8 may contain a condensed soup. Here, by manipulating the handle 13 at the time of need, the condensed soup in the portion container 8 can be mixed into the hot water such that the user is allowed to drink a warm soup. Further, the portion container 8 may contain a condensed beverage. In such case, by manipulating the handle 13 at the time of need, the condensed beverage in the portion container 8 can be mixed into a water such that the user is allowed to drink a cold beverage. Furthermore, the container 2 may contain a coffee, and the portion container 8 may contain, for example, a milk and/or sugar. There, the user, at the time of need, is allowed to drink coffee by mixing the milk and sugar thereinto. However, the content may be a substance other than a liquid. In fact, the content may be a granular substance such as sugar or the like, and it is preferred that the content be that having a fluidity such as a liquid or granular substance.

According to the present embodiment, provided is the portion container compression system capable of pushing out the content of the portion container 8 by squeezing the corresponding portion container 8 that has been aligned to the receiving portion 51 of the mouth body 10 serving as a system main body. Particularly, the system includes the receiving portion 51 for installing the portion container 8, and formed on the front region of the portion container 8 is the peeling induction portion 65 serving as an easily unsealable portion. More particularly, the portion container 8 is formed into the asymmetric shape in the front-back direction, and provided on the receiving portion 51 is the central holding claw 53 as a misalignment-prevention portion allowing the front region of the portion container 8 to be aligned to the receiving portion 51, but preventing the back region of the portion container 8 from being aligned to the receiving portion 51. Therefore, even when the portion container 8 is positioned on the central holding claw 53; under the left and right receiving claw portions 54; or back to front, the user is not only able to recognize the misalignment of the portion container 8 due to the fact that the misplaced portion container 8, for example, cannot be squeezed at all or squeezed by an intended degree, but also allowed to safely use the system without contaminating clothes or other surrounding items.

Also, according to this embodiment, the central holding claw 53 provided in the receiving portion 51 serves as a misalignment-prevention portion allowing the user to notice the misalignment of the portion container 8. That is, the front region of the flange portion 62 of the portion container 8 with the peeling induction portion 65 positioned downward is allowed to be positioned to the receiving portion 51. Meanwhile, when positioning the back region of the flange portion 62 of the portion container 8 to the receiving portion 51, since the area of contact between the back region of the portion container 8 and the receiving portion 51 is smaller than the area of contact between the front region of the portion container 8 and the receiving portion 51, the user is allowed to recognize the misalignment of the portion container 8 whenever it occurs.

Furthermore, according to the present embodiment, provided is the portion container compression system capable of pushing out the content of the portion container 8 aligned to the receiving portion 51 of the mouth body 10 as a system main body, by swinging the handle 13 and then allowing the same to squeeze the portion container 8. Particularly, the system includes the receiving portion 51 for installing the portion container 8, and formed on the front region of the portion container 8 is the peeling induction portion 65 serving as an easily unsealable portion. More particularly, the receiving portion 51 is disposed away from the center and toward the handle 13. Here, the receiving portion 51 is so configured that the portion container 8, when misaligned, will fall in the region opposite to where the handle 13 is provided upon swinging the handle 13. That is, when swinging the handle 13, the misaligned portion container 8 will fall in the area of the communication passage 17 that is close to the region opposite to where the handle 13 is provided, thereby making it impossible or hard for the portion container 8 to be squeezed, thus allowing the user to easily notice the misalignment.

Furthermore, according to the present embodiment, the portion container 8 has the substantially flat bottom surface portion 66. Particularly, the portion container 8 is so aligned to the receiving portion 51 that the bottom surface portion 66 slants toward the handle 13. In this way, since the portion container 8 is to be obliquely aligned to the receiving portion 51, and since the substantially flat but slanting bottom surface portion 66 is to be squeezed by swinging the handle 13, the portion container 8 can be easily squeezed, thus preventing the portion container 8 from being misaligned. Further, according to claim 1, misalignment can be prevented when positioning the portion container 8 to the receiving portion 51 with the front region of the portion container 8 pointing obliquely downward. Furthermore, according to claim 2, when the obliquely positioned portion container 8 has been misaligned, it will easily fall in.

Furthermore, according to the present embodiment, the mouth body 10 serving as a system main body can be used as a mouth for drinking and a plug body. That is, the user is able to drink a beverage from the communication passage 17 that serves as a hole and is formed in the region opposite to where the handle 13 is provided, and the mouth hole 58 is used as a flow channel, thus allowing the system to be used as a beverage container.

The effects of the present embodiment are as follows. That is, provided is the portion container compression system capable of pushing out the content of the portion container 8 by squeezing the corresponding portion container 8 that has been aligned to the receiving portion 51. Particularly, the system includes the receiving portion 51 for obliquely aligning the portion container 8, and formed on the front region of the portion container 8 is the peeling induction portion 65 serving as an easily unsealable portion. More particularly, the portion container 8 is to be positioned between the receiving portion 51 and the rear wall 14K that is located on the rear side of the receiving portion 51, and the lower space 83 is to be formed below the peeling induction portion 65 as a result of positioning the front region of the portion container 8 to the receiving portion 51. For these reasons, the portion container 8 is subjected to compression forces applied by both the receiving portion 51 and the rear wall 14K that is located on the rear side thereof. Therefore, the portion container 8 is allowed to be held in a balanced manner, and the seal lid 63 at the bottom can reliably swell due to the compression forces such that the content of the portion container 8 can then be ejected from the easily unsealable portion.

Further, since the splashing space 102 for the content of the portion container 8 to be ejected therein is formed beyond the peeling induction portion 65 along the extended line 101, the content ejected can hardly be splashed upward.

Furthermore, the receiving portion 51 includes: the receiving claw portions 54, 54 that are formed in the left-right direction; and the central holding claw 53 that is formed in the center. Particularly, when positioned to the receiving claw portions 54, 54, the flange portion 62 which is a part of the portion container 8 is to be located below the central holding claw 53, thereby allowing the left and right receiving claw portions 54, 54 and the central holding claw 53 to hold therebetween the flange portion 62 of the portion container 8, thus making it difficult for the portion container 8 to rise even when compressed from above.

Furthermore, since the rear wall 14K includes the bulging portion 14B formed by partially expanding the inner circumference of the upper protruding wall 14, and since this bulging portion 14B includes the placement surface 14S, the flange portion 62 can be stably supported by this placement surface 14S.

Also, as an effect of the embodiment, provided is the portion container compression system including the mouth body 10 as a system main body. Specifically, the mouth body 10 has: the receiving portion 51 for installing the portion container 8; and the rotatable handle 13. The portion container 8 includes the peeling induction portion 65 as an easily unsealable portion, and is to be compressed, when aligned to the receiving portion 51, by swinging the handle 13. That is, by applying the principle of leverage, the portion container 8 can be squeezed by the handle 13, thereby improving a convenience and allowing the system to be formed compact as compared to a rotary apparatus. Further, the handle 13 can also be used to carry the system, thus improving a convenience as well.

Moreover, since the portion container 8 is to be obliquely aligned to the receiving portion 51, the content ejected therefrom hardly splashes. In fact, not only the flange portion 62, but the bottom surface portion 66 is to be obliquely positioned as well.

Further, since the receiving portion 51 is located below the rotation center shaft 34 of the handle 13, the portion container 8 is to be pushed by the handle 13 having the rotation center shaft 34 that is located above the receiving portion 51, thereby causing the portion container 8 to be compressed by the pushing force of the handle 13, thus allowing forces to be applied easily.

Furthermore, since the mouth body 10 serving as a system main body can be disposed on or attached to the container 2, a condensed beverage of the squeezed portion container 8 can be diluted by a water or hot water. Here, when diluted by water, ice can be added thereto whenever necessary, thus making it possible to prepare a beverage.

Furthermore, since there is provided the mouth portion 14A that is disposed in the region above the receiving portion 51 and severs as a mouth for drinking, the user is allowed to directly drink the beverage in the container 2, thus further improving the convenience.

Furthermore, since the lid body 71 with the water stop function is provided on the upper portion of the mouth body 10 serving as a system main body, the beverage prepared can be carried with the lid body 71 shut, thus further improving the convenience.

Furthermore, since the handle 13 is fixed by the locking mechanism 40 at the initial position, the system can be carried and the user can drink the beverage with the handle 13 being fixed.

Furthermore, since the locking mechanism 40 is disposed under the handle 13, not only the handle 13 can be easily unlocked, but a superior design feature can be achieved with a small amount of influence on the appearance.

Furthermore, since the cutout section 70 is formed in the region of the mouth portion 14A for drinking that corresponds to a swinging location of the handle 13, not only the rotational center of the handle 13 can be lowered, but the portion container 8 is allowed to be installed in a deeper location, thus achieving a high designability and saving space.

Moreover, as an effect of the embodiment, since the mouth body 10 and the ring portion 11 are detachably attached to the container 2, the mouth body 10 and the ring portion 11 can be removed therefrom and then washed. Also, since the ring portion 11 is provided with the ring portion-side cutout section 70B formed at the swinging location of the handle 13, a wide swinging range of the handle 13 can be secured. The locking mechanism 40 serves to automatically lock the handle 13 once the unlocked handle 13 has been swung to the initial position. Particularly, the locked state is established as the downward protrusion 42 engages with the through hole 47. Further, since the locking member 41 of the locked state is substantially received in the concave portion 43, the handle 13 is superior in appearance and design. Further, since the protrusions 46D are formed on the locking member 41, the location of the control portion 46S can be easily identified by touching the protrusions 46D. Moreover, since there is also provided the lid body 71, the cutout section 70 can be hidden thereby. In addition, since the concave portion 43 is provided in the lower region of the handle 13, the locking mechanism 40 can be received therein.

Second Embodiment

FIG. 18 shows in detail a second embodiment of the present invention, in which elements identical to those of the first embodiment are denoted by identical symbols, and the descriptions thereof are thus omitted. In this embodiment, the bottom surface portion 66 is not parallel to the flange portion 62, but formed at a given angle thereto. Particularly, the bottom surface portion 66 is so configured that the region opposite to where the peeling induction portion 65 is formed slants toward the flange portion 62. Here, by swinging the handle 13 toward the compression direction, the portion container 8 can be compressed as the curved upper surface 36J pushes the bottom surface portion 66 substantially parallel.

However, the present invention is not limited to the aforementioned embodiments. In fact, various modified embodiments are possible within the scope of the present invention. For example, although the aforementioned embodiments use a substantially cylindrical container and system main body, a square container and system main body may be used as well. Further, the easily unsealable portion is not limited to that disclosed in the aforementioned embodiments. In fact, various kinds of easily unsealable portions can be used. Furthermore, the rotation center shaft integrally disposed in the handle may be rotatably attached to the container body. In addition, with regard to claim 1, the portion container may be squeezed not by the handle, but by a conventional method as set forth in prior arts.
