1. Field
This invention relates to fluid containers made of a pliable material and more particularly relates to an apparatus, system and method for enhancing the structural integrity of a fluid container made of a pliable material to avoid a collapse of the material comprising the fluid container.
2. Description of the Related Art
Fluid containers made of pliable materials are used to contain a variety of liquids for personal consumption. For example certain artificially and naturally flavored juices are packaged in a pliable pouch made of a flexible plastic material. Each pliable pouch contains about six to seven fluid ounces of juice, enough juice to quench an average user's thirst.
Other consumable products are packaged in pliable containers. For example, certain frozen snack foods are packaged in a pliable plastic tube. The pliable tube is filled with a flavored sugary liquid and is sealed at each end. After the flavored liquid is frozen a user can cut off the top and eat the frozen snack out of the top of the tube, like a Popsicle without a stick. Many other fluid materials are packaged in pliable plastic tubes such as single shot energy supplements or drinks, yogurt, powdered substances for mixing with water or other liquids, or other edible items.
Pliable containers are not limited to edible materials. For example, pastes and lotions for dermatological uses are often contained within sealed pliable containers. Similarly, glues and other viscous materials are often sold in flexible or pliable containers.
Pliable containers for containing liquids provide several advantages over rigid containers. First, in terms of disposal the flexible material of a pliable container allows the pliable container to be easily flattened before disposing of the container. Additionally, a pliable container may use less material than a rigid container. Manufacturing processes for creating a pliable container may also be more economically efficient than the plastic molding techniques used in creating rigid containers.
Despite the advantages associated with pliable containers, there use is limited to applications where the structural integrity of the container is not an issue. When a pliable container is used to contain an edible product certain precautions are typically taken to avoid spilling the contents of the container on the user. For example, when a pliable container is used to contain an artificial or naturally flavored juice, a straw is provided to consume the juice.
In the frozen snack food example the structural integrity of the pliable container is not an issue as long as the material within the container remains frozen. However, once the material within the container thaws, the user risks spilling the material from the container if the container folds or bends due to the weight of the material in the container.
Many of the edible items sold in pliable containers, such as the frozen snack food or the natural or artificially flavored juice, are directed at children. Often marketers of products aimed at children include gifts or other novelty features in the packaging of a product to encourage children to request the product. For example, children's cereal often includes a surprise in the cereal. Similarly, the packaging of the children's cereal often includes games, comics, or other novelty features. Generally, the gift or novelty item adds nothing of value to the actual product or packaging and is simply used as marketing tool.
From the foregoing discussion, it should be apparent that a need exists for an apparatus, system, and method that enhances the structural integrity of a fluid container made of a pliable material to avoid a collapse of the material comprising the fluid container. Beneficially, such an apparatus, system, and method would incorporate a novelty feature into the packaging.
The present invention has been developed in response to the present state of the art, and in particular, in response to the problems and needs in the art that have not yet been fully solved by currently available liquid containers made of pliable materials. Accordingly, the present invention has been developed to provide an apparatus, system, and method for containing a liquid that overcome many or all of the above-discussed shortcomings in the art.
The apparatus to contain a fluid is provided with a fluid receiving sleeve, a support member and a support member coupling. The fluid receiving sleeve is made of a pliable material having a structural integrity that may be overcome by a weight of a fluid when the fluid is located within the fluid receiving sleeve. In certain embodiments the fluid receiving sleeve includes a sidewall, a dispensing end, and a sealed end. The sealed end of the fluid receiving sleeve includes a liquid tight seal that keeps a fluid dispensed within the fluid receiving retained within the fluid receiving sleeve.
The support member is a substantially rigid rod for supporting the fluid receiving sleeve along the sidewall of the fluid receiving sleeve between the dispensing end and the sealed end. The substantially rigid rod is made of a material having a structural integrity sufficient to support the pliable material of the fluid receiving sleeve when the fluid receiving sleeve contains a fluid.
The support member coupling is configured to receive a support member to couple the support member to the fluid receiving sleeve when the support member is positioned in an engaged position within the support member coupling. In the engaged position the support member is removably coupled to the fluid receiving sleeve along the sidewall of the fluid receiving sleeve. The support member supports the fluid receiving sleeve when the support member is positioned in the engaged position. In this manner the structural integrity of the fluid receiving sleeve is maintained by the support member.
The support member, in one embodiment, is a support member receiving sleeve. The support member receiving sleeve is positioned next to the sidewall of the fluid receiving sleeve and is attached to the sidewall of the fluid receiving sleeve and separated from the fluid receiving sleeve by a seal. The support member receiving sleeve receives the support member within the support member receiving sleeve to couple the support member to the fluid receiving sleeve.
In certain embodiments the support member receiving sleeve includes a support member sidewall, a support member receiving end, and a support member sealed end. The support member sidewall has a length substantially a same length as the sidewall of the fluid receiving sleeve. In an exemplary embodiment the support member sidewall of the support member receiving sleeve is attached to the sidewall of the fluid receiving sleeve along the entire length of the sidewall of the fluid receiving sleeve.
In a further embodiment, the support member coupling is a plurality of retention sheaths attached to the sidewall of the fluid receiving sleeve at attachment points along the sidewall of the fluid receiving sleeve. The plurality of retention sheaths receive the support member. In such an embodiment the support member supports the fluid receiving sleeve at the attachment points on the sidewall of the fluid receiving sleeve.
In another embodiment, the support member is a hollow tube having a length sufficient to substantially span a length of the fluid receiving sleeve between the dispensing end and the sealed end. The hollow tube includes a slot along the length of the hollow tube. The slot in the hollow tube receives a portion of the sidewall of the fluid receiving sleeve to attach the hollow tube to the sidewall of the fluid receiving sleeve.
In one embodiment, the apparatus includes a rolling sleeve attached perpendicular to the fluid receiving sleeve. The rolling sleeve receives a rolling member to assists a user in rolling the fluid receiving sleeve to dispense a fluid contained within the fluid receiving sleeve. The rolling member may be a separate item or, in certain embodiments, the rolling member may be the support member removed from the support member coupling.
The apparatus, in one embodiment, includes a translucent fluid contained within the fluid receiving sleeve. In certain embodiments the support member may illuminate the translucent fluid disposed within the fluid receiving sleeve. In such an embodiment, the support member may be a single use translucent plastic tube containing isolated substances which when combined illuminate through a chemical reaction induced chemiluminescence. In another embodiment, the support member includes a power source and a light emitting diode. The power source is electronically coupled to the light emitting diode to illuminate the support member. The illuminated support member illuminates the translucent fluid contained within the fluid receiving sleeve.
Another embodiment of an apparatus to contain a fluid includes a pliable tube separated into a fluid receiving sleeve, a support member receiving sleeve, and a rolling sleeve. The fluid receiving sleeve is made of a pliable material having a structural integrity that may be overcome by a weight of a fluid when the fluid is disposed within the fluid receiving sleeve. The fluid receiving sleeve includes a sidewall, a dispensing end, and a sealed end. The sealed end has a liquid tight seal that keeps a fluid contained within the fluid receiving sleeve when fluid is placed within the fluid receiving sleeve.
The support member receiving sleeve is positioned next to the fluid receiving sleeve and is attached to and separated from the sidewall of the fluid receiving sleeve by a liquid tight seal. The support member receiving sleeve receives to receive a support member within the support member receiving sleeve.
The rolling sleeve is positioned perpendicular to the fluid receiving sleeve and the support member receiving sleeve. The rolling sleeve is configured to receive a rolling member to assists a user in rolling the fluid receiving sleeve to dispense a fluid contained within the fluid receiving sleeve.
In certain embodiments, the apparatus also includes a support member removably received within the support member receiving sleeve. The support member is a substantially rigid rod for supporting the fluid receiving sleeve along a length of the sidewall of the fluid receiving sleeve between the dispensing end and the sealed end. The substantially rigid rod is made of a material having a structural integrity sufficient to support the pliable material of the fluid receiving sleeve when a fluid is disposed within the fluid receiving sleeve and when the support member is positioned in an engaged position. In the engaged position the support member is received within the support member receiving sleeve. The support member supports the fluid receiving sleeve when the support member is positioned in the engaged position so that the structural integrity of the fluid receiving sleeve is maintained and so that any fluid contained within the fluid receiving sleeve does not spill from the fluid receiving sleeve.

Examples of fluids 104 contained within prior art fluid containing and dispensing apparatus' 100 include flavored water, single shot energy supplements or drinks, yogurt, or other edible items. In certain embodiments a similar pliable tube 102 is used to contain premeasured powdered substances for mixing with water or other liquid. As used herein, the term “fluid” is defined as any substance which is capable of flowing. Thus, fluids discussed herein are not limited to liquid fluids. Additionally, the term “fluid” includes frozen substances which, while not capable of flowing in the frozen form, are capable of flowing in a thawed form.
Fluids 104 contained within the pliable tube 102 typically have a mass that can overcome the structural integrity of the pliable tube 102 causing the pliable tube to bend under the weight of the fluid 104. Depending on where the user is holding the pliable tube 102, the pliable tube can fold and empty any fluid 104 that is contained within the pliable tube 102 above the point of the fold. For example, if a user holds the pliable tube 102 at point 112 the weight of the fluid 104 contained above point 112 may cause the pliable tube 102 to fold at point 112. Any fluid 104 contained within the pliable tube 102 between point 112 and the top end 110 of the pliable tube 102 may then spill from the opening 109 in the pliable tube 102. One of skill in the art will recognize that the point at which the pliable tube bends or folds may not be a static position and is dependent on several factors such as the weight of the fluid 104 contained within the pliable tube 102, the state of the fluid 104 (solid, semisolid, liquid, etc.), and the rigidity of the material that makes up the pliable tube 102. Thus, the folding point 112 may be may be at different positions along the length of the pliable tube 102 depending on the above stated factors as well as others.
In the embodiment illustrated in
The fluid receiving sleeve 202 includes a sidewall 210, a dispensing end 212, and a sealed end 214. In certain embodiments the dispensing end 212 and the sealed end 214 may be about the same length and the length of the sidewall 210 may be substantially longer than the length of the dispensing end 212 and the sealed end 214. For example, in an exemplary embodiment the length of the dispensing end 212 may be in the range of about one inch to about two inches, the length of the sealed end 214 may be in the range of about one inch to about two inches, and the length of the sidewall 210 may be in the range of about nine and one half inches to about eleven and one half inches. In another exemplary embodiment the length of the dispensing end 212 may be in the range of about one inch to about two inches, the length of the sealed end 214 may be in the range of about one inch to about two inches, and the length of the sidewall 210 may be in the range of about eighteen inches to about twenty inches. Of course, one of skill in the art will recognize that these are exemplary measurements only. Therefore, the dimensions of the fluid receiving sleeve 202 may vary without departing from essential spirit of the present invention.
In certain embodiments the fluid receiving sleeve 202 may be sized to receive a premeasured amount of a substance such as a premeasured medication. In one embodiment the fluid receiving sleeve 202 may be sized to receive a premeasured amount of liquor mixed in a flavored mixer. The premeasured amount of liquor may be measured according to local or federal laws or regulations regarding dispensing liquor.
In certain embodiments the sealed end 214 of the fluid receiving sleeve 202 may have a length that is shorter than the length of the dispensing end 212 such that the apparatus 200 is V shaped when the apparatus 200 is viewed with the dispensing end 212 at the top of the apparatus 200. In another embodiment the sealed end 214 of the fluid receiving sleeve 202 may have a length that is longer than the length of the dispensing end 212 such that the apparatus 200 has an inverse V shape when the apparatus 200 is viewed with the dispensing end 212 at the top of the apparatus 200.
The sealed end 214 of the fluid receiving sleeve 202 includes a seal 216 for retaining the fluid 208 within the fluid receiving sleeve 202. In certain embodiments the seal 216 of the sealed end 214 may be accomplished through use of glues or other sealing substances injected or inserted into the fluid receiving sleeve 202. In another embodiment the seal 216 may be accomplished through plastic welding. Examples of plastic welding techniques which may be used to seal the fluid receiving sleeve include hot gas welding, speed tip welding, extrusion welding, contact welding, hot plate welding, high frequency welding, ultrasonic welding, vibration friction welding, spin welding, laser welding, solvent welding, or other plastic welding techniques.
In the embodiment illustrated in
The sidewall 210 of the fluid receiving sleeve 202 is made of a pliable material that may deform under a weight applied by fluid 208 contained within the fluid receiving sleeve 202. Thus, in certain embodiments a fluid 208 contained within the fluid receiving sleeve 202 may have a mass that can overcome the structural integrity of the pliable material of the sidewall 210. In one embodiment the fluid 208 contained within the fluid receiving sleeve 202 may be frozen and thus provide support to the fluid receiving sleeve as long as the fluid 208 remains frozen. Once the fluid 208 contained within the fluid receiving sleeve 202 thaws, the fluid 208 may no longer support the fluid receiving sleeve 202. Where the dispensing end 212 of the fluid receiving sleeve 202 is open, the fluid 208 may spill from the fluid receiving sleeve 202 when the weight of the fluid 208 overcomes the structural integrity of the pliable material of the sidewall 210.
In certain embodiments the sidewall 210 of the fluid receiving sleeve 202 is continuous such that the sidewall is tubular. In another embodiment, one side of the sidewall 210 may include a separating seal 218 running the length of the sidewall 210 from the sealed end 214 to the dispensing end 212. The separating seal 218 creates a liquid tight seal that separates a support member receiving sleeve 220 from the fluid receiving sleeve 202. Thus, in certain embodiments fluid 208 placed within the fluid receiving sleeve 202 is maintained within the fluid receiving sleeve 202 by the liquid tight seal 216 at the sealed end 214 and the liquid tight seal of the separating seal 218 running the length of the fluid receiving sleeve 202.
To maintain the structural integrity of the fluid receiving sleeve 202 a support member 202 is attached to the fluid receiving sleeve 202. The support member 202 is attached to the fluid receiving sleeve 202 by a support member coupling 206. In the embodiment illustrated in
The support member receiving sleeve 220 is positioned next to the sidewall 210 of the fluid receiving sleeve 202. The support member sleeve sidewall 224 of the support member receiving sleeve 206 is attached to the side wall 210 of the fluid receiving sleeve 202. As discussed above, in certain embodiments a separating seal 218 separates the sidewall 210 of the fluid receiving sleeve 202 from the support member sleeve sidewall 224 of the support member receiving sleeve 220.
The support member sealed end 228 of the support member receiving sleeve 220 may be sealed by a seal 222 at one or both ends to keep the support member 204 secure within the support member receiving sleeve 220. In certain embodiments the seal 216 at the sealed end 214 of the fluid receiving sleeve 202 may continue across the support member sealed end 228 of the support member receiving sleeve 220 to seal the end of the support member receiving sleeve 220. One of skill in the art will recognize that in certain embodiment it may be unnecessary to provide a liquid tight seal on the support member receiving sleeve 220 because in certain embodiments the support member receiving sleeve 220 may contain solid material or item such as a support member 204. Thus, in one embodiment the liquid tight seal 216 at the sealed end 214 of the fluid receiving sleeve 202 may only seal the fluid receiving sleeve 202 and a separate non-liquid-tight seal 222 may be applied to the support member receiving sleeve 220 to keep the support member 204 in the support member receiving sleeve 220.
In one embodiment the support member receiving end 226 of the support member receiving sleeve 220 may be open as illustrated in
The support member 204 is slideable within the support member receiving sleeve 220 such that the support member 204 can be withdrawn from the support member receiving sleeve 220 in a disengaged position or inserted all the way into the support member receiving sleeve 220 in an engaged position. In certain embodiments the support member 204 may be considered to be in an engaged position when the support member 204 is inserted far enough into the support member receiving sleeve 220 that the support member 204 provides support to at least one half of the fluid receiving sleeve 202. In other embodiments the support member 204 may support only a portion of the fluid receiving sleeve 202 in the engaged position.
In one embodiment, the support member receiving sleeve 220 has a length that is about the same as a length of the fluid receiving sleeve 202. In such an embodiment the support member 204 may also have a length that is about the same length as the support member receiving sleeve 220 and the fluid receiving sleeve 202. In an exemplary embodiment, the support member 204 is a substantially rigid rod having a length in a range of about seven to about nine inches and a diameter of about one eighth of an inch to about three sixteenths of an inch. Of course, one of skill in the art will recognize that these are exemplary measurements only and that the dimensions of the support member 204 may vary without departing from essential spirit of the present invention. In one embodiment the support member receiving sleeve 220 couples the support member 204 to the fluid receiving sleeve 202 along substantially the entire length of the sidewall 210 of the fluid receiving sleeve 202 providing support to the fluid receiving sleeve 202 along substantially the entire length of the fluid receiving sleeve 202.
The support member 204 is made of a rigid material having a structural integrity sufficient to support the fluid receiving sleeve 202 when the fluid receiving sleeve contains a fluid 208 having a mass sufficient to overcome the structural integrity of the fluid receiving sleeve. In certain embodiments the support member 204 is a substantially rigid rod having a structural integrity sufficient to support the pliable material of the fluid receiving sleeve 202 when a fluid 208 is disposed within the fluid receiving sleeve 202.
In the embodiment illustrated in
In one embodiment the retention sheaths 312 may attach directly to the sidewall 310 of the fluid receiving sleeve 302. In another embodiment, one side of the sidewall 310 may include a separating seal 318 and the retention sheaths 312 may be attached to the sidewall 310 of the fluid receiving sleeve 302 by the separating seal 318.
The embodiment illustrated in
In certain embodiments, the bottom end retention sheath 312d may include a seal 322 that keeps the support member 304 from passing all the way through the bottom end retention sheath 312d. In another embodiment the top end retention sheath 312a may also include a seal (not shown) that keeps the support member 304 from being removed from the top end retention sheath 312a. In use, when a user wishes to remove the support member 304, the user may remove the seal 322 from retention sheath 312d or the seal (not shown) from retention sheath 312a to access the support member 304.
As with the embodiment illustrated in
In certain embodiments the apparatus 400 may include a rolling sleeve 412 that is perpendicular to the fluid receiving sleeve 402 and the support member receiving sleeve 420. In certain embodiments the rolling sleeve 412 is open at each end 414 and 416. The rolling sleeve 412 is configured to receive a rolling member to assist a user in rolling the fluid receiving sleeve 402 to dispense the fluid 408 contained within the fluid receiving sleeve 402. In certain embodiments the apparatus may include a separate rolling member (not shown) that is received within the rolling sleeve. In the embodiment depicted in
In one embodiment the rolling sleeve 412 is separated from the fluid receiving sleeve 402 and the support member receiving sleeve 420 by a seal 416. The seal 416 may be substantially similar to the seal 216 described in relation to
The apparatus 400 depicted in
In
To create the rolling sleeve 512 a flap 530 is folded at line 532 in the direction indicated by arrows 532 and 534. One of skill in the art will recognize that in certain embodiments the line 532 may not actually be physically located on the pliable tube. Rather, line 532 is simply illustrative of a point at which to fold the flap 530. In other embodiments the pliable tube 500 may include a line illustrated thereon to aid in manufacturing the apparatus 400 for containing a fluid 408. The point at which the flap 530 is folded (line 532 as illustrated in
Once the flap 530 has been folded at the correct position (line 532 as illustrated in
As discussed above, in certain embodiments, such as the embodiment illustrated in
Once the fluid receiving sleeve 502, the support member receiving sleeve 520 and the rolling sleeve 512 have been formed, a fluid such as fluid 408 may be inserted into the fluid receiving sleeve 502. The top end 542 of the fluid receiving sleeve 502 may then be sealed using a glue or other sealing substance or by any of the plastic welding techniques discussed above. In certain embodiments a support member such as support member 404 may be inserted into the support member receiving sleeve 520 and the top end 544 of the support member receiving sleeve 520 may be sealed using a glue or other sealing substance or by any of the plastic welding techniques discussed above. One of skill in the art will recognize that in certain embodiments the same seal may seal both the top end 542 of the fluid receiving sleeve 502 and the top end 544 of the support member receiving sleeve 520.
The hollow tube 716 of the support member coupling 706 has an inner diameter sufficient to receive the support member 704. As further illustrated in
The fluid contained within the fluid receiving sleeves according to the various embodiments described herein is clear or translucent and allowing light to pass through the fluid. Additionally, in certain embodiments, the pliable material of the fluid receiving sleeves and support member receiving sleeves described herein may also be translucent or clear. Thus, the support member 904, in certain embodiments, may be used to illuminate the neighboring fluid in the fluid receiving sleeve through the clear or translucent pliable material of the fluid receiving sleeve.
The electrical components compartment 1014 houses the electrical components necessary to illuminate the illumination portion 1016 of the support member 1004. In certain embodiments the electrical components of the support member include a light emitting diode 1006 and a power source 1002. The power source 1002 may be any standard electrical battery as is known in the art. The light emitting diode 1006 is electrically coupled to the power source 1002 by two leads 1008 and 1010. In certain embodiments the support member 1004 also includes a push button electrical switch 1010 to turn on and off the light emitting diode 1006. One of skill in the art will recognize other types of switches may be used in place of the push button electrical switch 1010. In certain embodiments the support member includes a spring 1012. The spring 1012 maintains contact with the power source 1002 when the support member 1004 is moved such that the electrical connection between the power source 1002 and the light emitting diode 1006 is not lost.
The illumination portion 1016 of the support member 1004 may include a clear or translucent material that allows light to pass through the illumination portion 1016. In certain embodiments the illumination portion 1016 may be colored such that the light passing through the translucent material of the illumination portion 1016 is altered. In another embodiment the illumination portion 1012 may be white or clear and different colored light emitting diodes 1006 may be used to illuminate the illumination portion 1016 of the support member 1004 in a particular color.
The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
