RELEASABLE CONTAINER CAP

Abstract

A container has an improved releasable cap that is releasable with upward movement of the cap. A coupler also couples the cap to the container and provides for a stowed position in which the cap does not interfere with use of the container, and maintains the cap in a connected to configuration with the container at all times.

Description

TECHNICAL FIELD

The present disclosure relates to caps for containers for fluids such as beverages and others. More particularly, the present disclosure relates to a releasable container cap having releasable threads or other inward protruding male engagement features such as a rib or ring. The container cap may be operatively coupled at all times with the container with a tether or similar coupling structure such that the cap cannot be lost or removed from the bottle.

BACKGROUND

Conventional containers such as beverage bottles have threaded caps that are removed by rotation. Removal of the cap can take several turns before the threads of the cap are disengaged from the threaded neck of the container, and for some, both hands are required for the operation. In some uses, for example when driving or otherwise occupied, conventional caps are challenging or inconvenient.

Additionally, caps are oftentimes misplaced from the bottle. This causes a loss of functionality of the bottle, and also reduces recycling compliance. However, caps are not easily tethered to a bottle without the tethers becoming an interference, and tethers even more cumbersome for use with bottles having a cap that is removed by twisting movement of the cap.

Additionally, threaded caps that are tethered to the bottle often place the opened cap in a position that makes the bottle awkward or impractical to drink from or pour.

An improved container cap is needed.

An improved releasable container cap 10 having releasable threads, according to at least one embodiment, is shown in FIGS. 1-8. From a use perspective, the container cap 10 can be used conventionally in that, once mounted on the threaded neck 2 of a container 4, a non-limiting example of which is shown in FIG. 3 for illustration of use of the container cap 10. The container 4 is partially illustrated, showing particularly its top end, representing that the container can have any volume and overall size. The cap 10 can be removed by user action rotating the cap 10 around its longitudinal axis 12. The rotation causes the cap 10 to advance along the neck 2 of a container, as internal helical threads of the cap 10 engaging corresponding external threads 6 of the container neck 2 advance the cap 10, until the cap 10 is removed. A tamper-proof security ring 14 attached to the sidewall sections of the main body 20 of the cap 10 by frangible strips 16 is removed from the main body by breaking of the strips as the cap 10 is removed from the container. Flaps 18 (FIG. 1) along the interior of the tamper-proof ring 14 keep the ring centered beyond a fixed ring 8 (FIG. 3) on the neck 2 to keep the ring 14 on the container 4 as the cap 10 is removed.

Once removed or loosened by rotation, the cap 10 can be tightened to reseal a container by opposite rotation and threaded re-engagement. The cap 10 can be repeatedly used in this fashion.

The container cap 10 also has novel features advantageously improved over prior container caps 10 that are also used conventionally as just described. In particular, the cap 10 has releasable internal threads that are disengaged from the threaded neck of a container when unique tabs are pressed by user action, permitting the cap 10 to be removed without necessitating its rotation.

Describing now in detail the structural features of the container cap 10, the main body 20 has a generally circular top piece 22 defining a longitudinal end of the cap 10. Two sidewall sections 24 are connected to and integral with the top piece 22 along its circular perimeter and extend longitudinally therefrom to define an interior 26 (FIG. 6) of the cap 10 for receiving and engaging the threaded neck of a container in use. The exterior surfaces 30 of the sidewall sections 24 configured to be gripped, having longitudinally extending grip ridges 32 in the illustrated embodiment. The interior surfaces of the sidewall sections 24 each have a respective threaded portion 34 (FIG. 2, FIG. 7). The two threaded portions 34 of the two sidewall sections 24 cooperate to engage the threaded neck of a container in use as the top piece 22 seals the container. The threads 36 (FIGS. 7-8) of the threaded portions 34 can have an industry standard pitch or customized pitch to match a preferred use and container 4 such as that shown in FIG. 3.

Each sidewall section 24 is formed as a partial semicircle and thus wraps circumferentially around the longitudinal axis 12 by less than one hundred and eighty degrees. Thus, the circumferential ends 40 (FIG. 4) of the two sidewall sections 24 do not meet. Instead, each circumferential end 40 of each sidewall section 24 is spaced from an adjacent circumferential end 40 of the other sidewall section such that two diametrically opposed expandable gaps 42 are defined between the spaced circumferential ends 40. The gaps 42 are minimized in an engagement configuration of the cap 10, which is illustrated in the drawings, referring to the cap 10 in use or ready for use in engaging the threaded neck of a container and sealing the container.

A respective operable tab 50 spans each gap along the exterior of the cap 10. Each tab has two ends 52 (FIG. 4), each connected to a respective sidewall section 24 adjacent the circumferential end 40 of the sidewall section. A central part 54 of each tab 50, between the two ends 52 thereof, bulges radially outward over and spans a respective gap 42. The tabs 50 may be tapered as illustrated, reducing radially toward the top piece 22 of the cap 10 to provide a comfortable overall form and minimize the likelihood of snagging on other items when handled. Thus, as described and shown in the drawings, the tabs can be described as hollow protrusions in that each has an open interior space to allow its compression without interrupting the continuous perimeter of the cap and tabs combined.

The tabs 50 are diametrically opposed. A first diametric axis 60 between the two tabs 50 crosses the longitudinal axis 12 that defines the center of the cap 10. The tabs 50 are operated by user action, for example with an index finger and thumb, pressing them radially inward at the central parts 54 as represented by opposing pinching forces 62 in FIG. 5. This causes: the central parts 54 of the tabs 50 to move inward; the gaps 42 to be expanded; and the sidewall sections 24 to be flexed in radially outward opposite directions 72 along a second diametric axis 70 as represented in FIG. 4. In the illustrated embodiment of the cap 10, the first diametric axis 60, the second diametric axis 70, and the longitudinal axis 12 are mutually orthogonal.

As the sidewall sections 24 are flexed radially outward by user action pinching the central parts 54 of the operable tabs 50 radially inward, the threaded portions 34 of the two sidewall sections 24 are carried radially outward from the illustrated engagement configuration to disengage the threaded neck 2 of a container 4, permitting the cap 10 to be removed therefrom without rotation around the longitudinal axis by lifting the cap along the axis 12 away from the neck of the container. The sidewall sections are disallowed from flexing until the tamper-proof ring 14 is separated from the cap.

The threads 36 of the threaded portions 34 of the two sidewall sections 24 have tapered circumferential ends 38 (FIG. 8) to facilitate smooth use when the cap 10 is rotated and to facilitate disengagement when the tabs 50 are operated. The tabs 50, by spanning and thereby shrouding or overhanging the gaps 42, promote cleanliness from dust at the threaded neck of a container.

The cap 10 can be fabricated as a unitary item by, for example, injection molding. A resilient and durable material, such as plastic, can be used to facilitate multiple uses of the cap 10 on a host container. For example, once removed from a container by disengagement of the threads 36 by user force on the operable tabs 50, or the cap 10 can be returned to the container by rotation and threaded engagement to reseal the container multiple times. The internal threads taper in such a way that the cap may be forced onto the bottle neck by expanding the sidewalls as the cap is forced over the bottle neck threads.

In the above descriptions and in the drawing, threads protrude inwardly within the cap to engage threads that protrude outward from the bottle neck. Thus, threads are a particular type of male protrusions by which the cap engages the bottle neck. Other types of male protrusions can be used in other embodiments such that these descriptions and drawings relate as well to other such male protrusions. For example, rings or partial rings (non-helical) can be used as inward extending male protrusions in the cap to engage outward extending male protrusions on the bottle neck. Thus, although the illustrated embodiment has threads, simple male details can be used that can be snapped past and able to be cleared when the cap is squeezed. For example, a male standing rib similar to a thread but entirely horizontal.

After the tamper-proof ring has been broken, the cap may be replaced by snapping it on directly onto the bottle neck. As the male protrusions of the cap are pushed past the male protrusions of the bottle neck, the hollow protrusions allow the walls containing the male protrusions of the cap to flex outward as they ramp past the male protrusions of the bottle neck. The tamper-proof ring disallows this flexure by holding these walls in the original cylindrical form.

Another embodiment is illustrated in FIG. 9 through FIG. 17, in which an improved container assembly is provided and generally designated 110. The container assembly 110 includes a bottle 112 for including contents for edible consumption. In one or more embodiments, the bottle 112 may be a drink bottle, though any other consumable or even non consumables may be held within the bottle 112. The bottle 112 defines a bottle neck 114 extending from the container as is conventionally known. The bottle neck 114 is shown having a generally tapering cross-section, however, any appropriate configuration may be provided.

As illustrated, the bottle neck 114 defines a first circumferentially extending outwardly threaded portion 116, and a discontinuous second circumferentially extending outwardly threaded portion 120. The discontinuity between the first threaded portion 116 and the second threaded portion 120 is advantageous and will be described in greater detail further herein. Medial portions 122 between the first circumferentially extending outwardly threaded portion 116 and the second circumferentially extending outwardly threaded portion 120 is shown illustrated being free of threads. However, medial portion 122 may not be entirely free of threads, but instead have lesser radially extending threads.

A cap 124 is configured for being rotatably received on and engaged with the bottle neck 114. The cap 124 is illustrated in contact with the bottle neck 114. The cap 124 may be installed by pushing down onto the cap as will be described in more detail.

As illustrated well in FIGS. 13 and 14, the cap 124 defines a first circumferentially extending inwardly threaded portion 126, and a discontinuous second circumferentially extending inwardly threaded portion 130. A medial portion 132 between the first circumferentially extending inwardly threaded portion 126 and the second circumferentially inwardly extending threaded portion 130 is free of threads. The cap 124 is configured to engage and disengage the bottle neck 114.

Engagement occurs in a first engagement mode where an interference fit occurs between the outwardly extending threads 116, 120 of the bottle neck 114 and the inwardly extending threads 126, 130 of the cap 124. This first engagement mode is well illustrated in FIG. 11 and additionally in the cross-sectional view of FIGS. 14 and 15. This is similar to the conventional manner in which a bottle cap is engaged with a bottle neck.

Advantageously, disengagement occurs in a second engagement mode that is in response to general angular alignment of the medial portions 122 of the bottle neck 114 and the medial portions 132 of the cap 124 such that the threaded portions 120, 122 of the bottle neck 114 and the threaded portions 126, 130 of the cap 124 do not prohibitively restrict upward movement of the cap 124 in response to a user lifting the cap 124 off of the bottle 112. The user thus rotates the cap 124 until there is thread disengagement or the threads bump against a stop (as will be described later herein), and then pulls upwardly on the cap 124 to separate the cap 124 from the bottle. A tamper proof retaining ring 134 is received by the bottle neck 114. The tamper proof retaining ring 134 is similar in some aspects to tamper proof retaining rings known in the art. The tamper proof retaining ring 134 is initially coupled to a distal surface 138 of the cap 124, but is severed upon rotational movement of the cap 124 with rotational movement of the cap in a counter clockwise movement (relative to the drawings provided herein). Due to the angle of the threads 116, 120 on the bottle neck 114, rotation of the cap 124 thus imparts upwards movement of the cap 124 relative to the retaining ring 134, which causes the severing of the engagement between the retaining ring 134 and distal surface 138 of the cap 124, except for the remaining attachment of the couplers 142, which maintain attachment between the retaining ring 134 and the cap 124 (as described later herein). This severing may be aided by perforations or areas of weakened structure at the interface between the retaining ring 134 and distal surface 138 of the cap 124. Or otherwise any feature providing frangibility can be employed. The retaining ring 134 is engaged upwardly of a radially extending shoulder 140 from the bottle neck 114.

Advantageously, a coupler 142 extends between the retaining ring 134 and the cap 124. The coupler 142 is well illustrated throughout the Figures, but in particular with reference to FIGS. 9 and 10. The coupler 142 is illustrated as a two spaced-apart arm assembly extending from the retaining ring 134 to the cap 124, however, any appropriate configuration may be employed. The advantageous aspect is that the coupler 142 provides for hinged movement of the cap 124 relative to the bottle neck 114. This may be accomplished by providing sufficiently flexible material and construction to the coupler 142.

The coupler 142 provides for at least two main advantages. The coupler 142 allows for inversing movement of the cap 124 from an engaged position as illustrated in FIG. 11 to a stowed position as illustrated in FIGS. 12A and 12B in which the cap 124 is hingedly pivoted away from the bottle neck 114 and the distal surface 138 of the cap 124 is engaged with a bottom surface 144 of the radially extending shoulder 140. Thus, in the position and orientation, providing distance from the inverted cap and the distal edge of the bottle neck, illustrated in FIGS. 12A and 12B, the cap 124 is shown stowed so that the cap does not impede the ability of a user to tip the bottle 112 upwardly and consume or pour out the contents. Additionally, the cap 124 is always maintained in contact with the bottle 112 so that the cap 124 does not move into a position to the bottle 112 such that it impedes a user from accessing the bottle 112 for drinking or positioning the cap such that it impedes pouring. This advantageously provides for improved compliance with recycling since the cap 124 and bottle 112 will be recycled together. Additionally, it reduces littering associated with the much smaller cap 124 since the cap 124 and bottle 112 are always coupled together.

As illustrated with reference to FIG. 11 where the cap is shown engaged to the bottle neck and more particularly FIG. 12B, FIG. 11 shows a unique advantage of the pivot 154 which attaches to the distal portion of the cap 124, traverses radially in an outward direction then turns downward to traverse in the opposite radial direction. When the cap 124 is in its placed in the inverted position, this coupler configuration provides a controlled gap for the bottle shoulder 140 to occupy, thereby capturing the cap in this position by having segments of the coupler 154 above and below the bottle shoulder 140, as illustrated in FIG. 12B.

The user can then return the cap 124 to its proper position by inverting of the cap 124 back into a position generally illustrated in FIG. 9 and pushing downwardly onto the cap after aligning medial portions 122 and 132 in a manner that is generally the opposite of removal. Once the cap 124 has been pushed downwardly until the bottom surface 138 is proximal the retaining ring 134 at which time the interior, bottom surface of the top of cap 124 is bottoming out on the sealing edge of the bottle neck 112, the cap 124 is rotated clockwise to secure the cap 124 to the bottle neck 114 by engagement of threads 116, 120 and threads 126, 130.

Due to the fact that the threads 116, 120 of the bottle neck 114 are discontinuous and full circle rotations of the cap 124 are not required to disengage or engage the cap 124 with the bottle neck 114, the threads 116 and threads 120 do not lie within a same plane as is typical in the art. For example, as illustrated in FIG. 16, threads 116 may be positioned on a plane “A” and threads 120 on a plane “B,” and the planes are parallel but also spaced-apart. This advantageously increases overall structural integrity of the thread pattern. Additionally, the threads 116 and threads 120 can thus be inverse, such that it is the exact thread detail rotated one hundred and eighty degrees axially.

As illustrated in FIG. 17, a flat surface is positioned in the medial portion 122, such that there is no engagement of the cap 124 and bottle neck 114 in a rotation position where the inward facing threads of the cap 126 and 130 are aligned with the flat medial portion 122 of the bottle neck 114. A detent 146 may extend from a surface of the medial portion 122 of the bottle neck 114. The detent 146 is to maintain the overall cylindrical form such that the cap 124 does not elongate and disengage from the threaded portions 116 and 120 of the bottle neck 114.

As illustrated well within FIG. 15, the tamper proof retaining ring 134 may define a void 150 in which a portion of the coupler 142 is received in. The coupler 142 is configured to elongate upwardly in response to the user pulling upwardly on the cap. This is well illustrated in FIG. 9 in which the coupler 142 is elongated upwardly. The coupler 142 may include a pair of arms 152 as illustrated in FIG. 12B. The pair of arms 152 are configured for to bend at a pivot point 154 where the pivot point 152 is adjacent the shoulder 140 of the bottle neck 114 when the cap 124 is inversed into the stowed position.

Particular embodiments and features have been described with reference to the drawings. It is to be understood that these descriptions are not limited to any single embodiment or any particular set of features, and that similar embodiments and features may arise or modifications and additions may be made without departing from the scope of these descriptions and the spirit of the appended claims.

13. The cap of claim 12, wherein the coupler is configured to elongate upwardly in response to the user pulling upwardly on the cap.

14. The cap of claim 12, wherein the coupler comprises a pair of arms, wherein the pair of arms are configured for to bend at a pivot point, the pivot point being adjacent the shoulder of the bottle neck when the cap is inversed into the stowed position.

15. The cap of claim 12, wherein the pairs of arms are attached to the tamper proof retaining ring in an opposing direction within the same horizontal plane, such that during extension, together with the cap, the pair of arms form a void shaped as to receive the radial extending shoulder of the bottle without interference when the cap is in the stowed position.

16. The cap of claim 15, wherein the pair of arms are configured such that, when the cap is in the stowed position a portion of each of the arms is above the bottle shoulder and a portion of each of the arms is below the bottle shoulder, thereby capturing the bottle shoulder and retaining the cap in the stowed position.
