The invention relates to caps.

background

Bottled beverages, including water, soda and juice, have created hundreds of millions of industries around the world. The main container for storing and selling such beverages is a plastic bottle. Plastic bottles have been widely used due to various factors including low price, light weight, ease of use and durability. The plastic bottle is usually closed on top of it with a plastic cap, and the plastic cap is usually provided with a safety seal. The cap can be removed by twisting or tapping to expose the beverage in the bottle. Typically, such caps include a movable valve, such as a sports cap, to allow the user to seal the bottle and use the valve as a drinking aid like a straw.

Water soluble beverage blends have a wide range of commercial applications. A mixture, usually in the form of a flake or powder, allows the user to make a beverage by simply adding water. The consumer measures the indicated, or desired, amount of the mixture and mixes in water to make the beverage. A typical plastic water bottle is not suitable for such mixing because it is difficult to inject the powder through a narrow opening. This mixing action (using a small funnel) is easier to do at home, however, it is quite difficult to travel or do outdoor activities such as off-road. In addition, in order to complete this kind of squatting In the mixing made by the middle, the user needs to carry a bottle and a beverage mixture separately. It is also easy to incorrectly measure the amount of water or beverage mixture, thus producing a beverage that is too thick or too light.

In the prior art, beverage supplements such as vitamins, nutrients and other supplements are volatile when suspended in a fluid such as water. The effectiveness of such beverage additives in water decreases over time. Therefore, beverage manufacturers must over-enhance this beverage by adding additional vitamins, nutrients and other supplements to ensure that at least a minimum of efficacy is maintained at the time of consumption or expiration. This has led beverage manufacturers to increase the cost of raw materials, significantly shorten the shelf life of beverages, and prevent consumers from being convinced of the efficacy or nutritional value of such beverages.

The concept of a bottle or container top that includes a tank for storing a beverage additive is conventional. Various components have been disclosed in the prior art. However, some of these bottles or containers have one or more undesired features.

Detailed description

The invention relates to apparatus, systems and methods for making a cap. The apparatus, system and method can include one or more embodiments, or any combination. Features of any embodiment can be combined with other embodiments. In addition, the use of the words "top" and "bottom" does not limit the orientation of any element, and is merely for convenience of explanation.

One embodiment of the present invention relates to a storage tank space cap, which may be referred to as a storage bottle cap. As shown in Figures 1A-1D, the cap preferably includes a first portion 70 and a second portion 5 that are fixedly secured to each other. The first and second portions 70 and 5 can be hollow. As shown in FIG. 1A, the first portion 70 can be a topsheet 70 and the second portion 5 can be a backsheet 5. The backsheet 5 can include a chamber 16 for receiving the topsheet 70; a bottom seal 25 (also referred to as a pierceable seal 25); a surface for securing to a spiral top container; a spiral Top seal; and or a lock seal. The topsheet 70 can include a first hollow portion or reservoir 10 for receiving and storing beverage supplements. The reservoir 10 on the topsheet 70 is shaped to allow the reservoir 10 to act as a piercing member 75 for rupturing the closure. The two sheets may be constructed of an opaque material that blocks all light that would spoil the beverage additive. When the two sheets are secured together, a plurality of seals can be formed to prevent the beverage additive from spoiling due to heat, moisture, air, and other environmental factors. The seals also prevent the fluid in the bottle from prematurely mixing with the beverage additive. The two sheets may be made of a material such as plastic in an injection molding or the like. Other materials, including but not limited to polymeric resins, paper, glass, rubber, alumina, carbon, metal or mixtures of these materials, including plastics, can be used to achieve the advantages of the present invention.

In some embodiments, the piercing member 75 and the bottom seal 25 are configured such that the topsheet 70 and the backsheet 5 rotate relative to one another, causing the piercing member 75 to puncture to The bottom seal 25 is less than a portion (or in some embodiments). Thus, the bottom seal 25 can be pierced by the piercing member 75 by a simple turning or twisting action without pushing the topsheet 70 down into the backsheet 5. An advantage of such a cap is that no additional space divider is required between the topsheet 70 and the backsheet 5 to prevent downward movement of the piercing member 75 and thus does not cause premature breakage of the bottom seal 25. This reduces the amount of material used and also eliminates the extra step of removing the space divider before pushing the topsheet 70 down to break the bottom seal 25.

As shown in FIG. 2A, in some embodiments, the piercing member 75 can be shaped or configured such that it does not extend below any of the bottom seals 25 before the top and back sheets 70 and 5 are twisted relative to each other, but as in the first After twisting as shown in Figures 2B and 2C, it extends beyond at least a portion of the bottom seal 25. For example, the piercing member 75 and the bottom seal 25 can be configured such that their respective side walls have a similar shape such that the piercing member 75 and the bottom seal 25 have a corresponding or mating taper or angle prior to twisting. For example, the bottom seal 25 can have a taper/angle depending on its side wall, similar to or in conjunction with the taper/angle of the piercing member 75 depending on the shape of its side wall. The rotation or twist of the topsheet 70 relative to the backsheet 5 causes a portion of the sidewall of the piercing member 75 (such as the longer side wall of the piercing member 75) to extend under at least a portion of the bottom seal 25, Wear it. In other embodiments, the taper or angle of the piercing member 75 and the bottom seal 25 may be different, but rotation of the piercing member 75 causes at least a portion of the piercing member 75 to pierce the bottom seal 25.

Other piercing techniques can also be used to turn/twist the cap. Moreover, the taper and angle of the piercing member 75 relative to the bottom seal 25 can vary, and It is not limited to the embodiments or examples disclosed herein. A structure, method and/or system for piercing the piercing member 75 of the bottom seal 25 after the topsheet 70/piercing member 75 has been rotated or twisted by the piercing member 75 may also be used.

As shown in Fig. 3, the interface between the topsheet 70 and the backsheet 5 can be a locking mechanism such as a security lock 55 that prevents the topsheet 70 and the backsheet 5 from being twisted/rotated, or without applying a force. Inadvertently moved to each other before. For example, the security lock device can block the topsheet 70 and the backsheet 5 from rotating relative to each other until the user applies a twisting action to break or release the locking mechanism, and the topsheet 70 and the backsheet 5 are no longer locked together by the locking mechanism. A turning or twisting action can be applied to one of the two caps.

In some embodiments, the locking mechanism can include one or more releasable or rupturable molars that interconnect the top and backsheet 5 to prevent their free rotation. After applying a sufficient torsional force, one or more of the molars are loosened or broken so that the locking mechanism no longer prevents the topsheet 70 and the backsheet 5 from rotating relative to one another.

In some embodiments, the bottom seal 25 does not require a line of weakness. In other words, the bottom seal 25 as a whole has a relatively average strength/material, but can still be pierced by the hollow piercing member 75.

As shown in FIG. 1A, in some embodiments, the topsheet 70 includes a first side wall 12 and a second side wall 14 having different lengths to form a tapered or angled portion on the bottom of the piercing member 75. The rounded edge 100. For example, the topsheet 70 is shown in the cross-sectional view of Fig. 1A, and Fig. 1B is an external view of the topsheet 70. The topsheet 70 includes a hollow piercing member 75 formed for the outer wall 80 and having an angled circle on the bottom of the piercing member 75. Shaped edge 100. The angle of inclination of the angled rounded edge 100 is such that when the safety lock 55 is loosened or broken for a twisting action of the topsheet 70, for example, the topsheet 70 is rotated relative to the backsheet 5 and the angled rounded edge 100 is stabbed Piercing and breaking, and at least partially (or entirely) piercing and opening the bottom seal 25.

In some embodiments, due to the taper/angle of both the piercing member 75 and the bottom seal 25, rotation of the top and backsheets does not cause the bottom seal 25 to completely separate from the bottom. In these embodiments, when the piercing member 75 reaches its original position, it no longer extends below the bottom seal 25 due to its tapered shape with the bottom seal 25, when the piercing member 75 reaches its original position. It does not pierce the portion of the bottom seal 25. This allows the bottom seal 25 to remain at least partially connected to the bottom portion to prevent it from falling into the container.

The amount of rotation or twist required to rupture the bottom seal 25 is changeable and is not limited to a specific amount. For example, the closure-rupture rotation can be 90 degrees, 180 degrees, or 340 degrees. Alternatively, the closure-rupture rotation can be from 1 degree to 360 degrees.

(no)

In some embodiments, the amount of rotation after the lock mechanism is released may be limited by the top and/or another structural device on the backsheet. This structure suppresses the rotation of the topsheet 70 relative to the backsheet 5 even after the locking mechanism is released, exceeding a certain amount. In other embodiments, such a rotation of the restraining structure is not required, and therefore, the top and bottom sheets 5 are free to rotate relative to each other after the locking mechanism is released.

In some embodiments, the backsheet 5 also includes a separate locking mechanism as a security lock 55 to prevent the backsheet 5 from being attached thereto. Inadvertent rotation of the film 5 of the container. The safety lock 55 mechanism can also include one or more of the aforementioned gingival ridges. When the film 5 is rotated relative to the container, the security lock 55 mechanism is released by, for example, breaking or loosening the caries to allow free rotation of the film 5 relative to the container.

In some embodiments, the backsheet 5 further includes an outer wall or projection 48 that can be rotated onto the bottle 160 by having a loop or thread 35. The topsheet 70 can also include a projection 18.
