Description

Storage type bottle cap

Technical Field

The present invention relates to a reservoir type bottle cap, and more particularly, to a reservoir type bottle cap which can be removed from a liquid-containing bottle, can retain solid or liquid components in the reservoir type bottle cap, and can be easily dispersed into the bottle to be mixed with liquid components therein.

Background

Many products come in the form of concentrates, crystals or powders during the sale and are mixed with a liquid prior to consumption or use. These products include foods, pharmaceuticals, cosmetics, glues, polishes, cleansers, infant formulas, shakes, meat substitutes, nutritional powders, energy mixes, supplements, nutraceuticals, and other substances. Some of these products do not guarantee their stability, strength and effectiveness for a long time after mixing into a solution or suspension, but they can be stored for extended periods if stored separately from each other. This requires that the product be used immediately after mixing to prevent spoilage, or interactions, etc. Well-known illustrative examples include epoxy glue, nutritional products that add infant formula ferment.

At the same time, the busy and active lives have also fueled a need for the portability, disposability, and convenience of shipping packages for these products, which store pre-measured quantities of ingredients for mixing with pre-calculated quantities of solutions to ensure that desired solution concentrations are maintained. For manufacturers, sales planning for this type of product presents many challenges, and in order to provide a pair of two products to consumers in a single package, it is clearly desirable that the two components be sold as the same package, so that only a single package is required to store and use such a mixture separately.

Various challenges are also encountered by consumers in using these products. Consumers often purchase large containers or batches of infant formula, instant drinks, dietary supplements or nutritional powders. Such small individual serving portions of powder or ready-to-drink mixes must be used in combination with water or other suitable liquid. However, the inconvenience associated with using such large containers of powder or mixture is well known. The consumer must spend time measuring and placing the proper amount of liquid or powder in the container during this mess of mixing the powder and the liquid in the bottle, and then shaking, stirring or otherwise completely mixing the contents. In doing so, powders and/or powder-liquid mixtures often spill, soil and lose a portion of the product.

To address these challenges, containers have been designed with two compartments in which two components can be stored separately until they are desired to be mixed, at which point he can establish communication between the compartments so that the separated components can be moved from one compartment to the other. It is known in the art to provide a dispenser containing a concentrate of soluble material, the dispensing of which is accomplished by mixing a solute into a fixed amount of solvent, usually water. Typically, the interior of the container is divided into a space for storing the liquid and a space is selectively pierceable upon request by the consumer to mix the separately stored liquid and powder substances.

The invention patent No. cn201180030348.x discloses a dispensing bottle cap, which is mainly realized by a pressing puncture piece in the bottle cap, and a consumer presses and operates to tear a bottom flexible sheet before drinking so as to mix solid or powder formula with liquid in a bottle. But it has the following disadvantages in use:

(1) the drinking water can be mixed by the consumer through extra pressing during the use process, however, if the resistance is too large during the pressing process, the difficulty is caused to the consumer during the use process;

(2) during the production and manufacturing process, hot melting is required during assembly, so that the activity of some probiotics is influenced;

(3) in the process of manufacturing, the process is relatively complex and the cost is high when the components are assembled.

The invention patent with the patent number of CN201610982626.6 discloses a bottle cap for solid beverage, which comprises an upper cap and a lower cap, wherein the upper cap is sleeved inside the lower cap to form a containing cavity for containing and storing the solid beverage, a sealing film is arranged in the bottom of the lower cap, a piercing device capable of piercing the film is arranged in the upper cap, and matched thread structures are arranged in the lower cap and the upper cap. With a similar structure with a plurality of groups of threads in parallel, the following defects exist:

(1) the structure with a plurality of groups of threads coexisting is adopted in the production and manufacturing process, so that the manufacturing difficulty and the manufacturing cost of the product are greatly increased.

(2) If the mixing operation before drinking is carried out, such as pressing or rotating, and the operation of opening the bottle cap during drinking, no obvious limit exists, so that consumers are very easy to be confused and cannot drink normally, and if the consumers turn the upper-layer bottle cap to carry out the mixing operation, the lower-layer bottle cap is opened by mistake, so that the stored powder or the formula cannot be drunk normally.

Disclosure of Invention

In order to solve the above problems, the present invention provides a reservoir type bottle cap having a reverse structure, which not only can greatly simplify the operation of a consumer, but also has an advantage of preventing the liquid in the bottle or the substance in the reservoir from being mixed normally due to an erroneous operation. Specifically, because the bottle cap is of a reverse structure, a consumer firstly needs to reversely screw the bottle cap before drinking, so that the pre-stored powder or formula can fall into the bottle to be mixed with liquid, and the mixed beverage can be drunk after the consumer normally screws the bottle cap to open; in addition, the reservoir type bottle cap comprises a structure combining the locking fin and the locking groove, so that the opening of a normally twisted bottle cap which is not twisted reversely by a consumer can be effectively prevented, and the situation that substances in a storage reservoir can never fall into the bottle body before the substances are pierced is ensured. In addition, the structure of the invention is relatively simple, no complex thread structure is provided, and the process does not need heating sealing, thus avoiding influencing the activity of the probiotics.

A reservoir bottle cap, comprising: the upper cover 100, built-in 200, lower cover 300, built-in 200 is located between upper cover 100 and lower cover 300, and the upper surface of upper cover 100, the lateral wall of built-in 200 and the sealed film of lower cover 300 constitute the accommodation chamber, and the accommodation chamber contains the material that waits to mix in the liquid, its characterized in that: wherein the upper cover 100 comprises two first slope surfaces 101, first hooks 102 and an upper cover body 104, the built-in part 200 comprises two second slope surfaces 201, a limiting groove 203, a central piercing column 204 and a sealing ring 205, the lower cover 300 comprises a limiting block 302, a sealing film and second hooks 304, the two first slope surfaces 101 on the inner upper surface of the upper cover 100 can be matched with the two second slope surfaces 201 of the built-in part 200, the second slope surfaces 201 can be completely matched with the first slope surfaces 101 through rotation, the diameter of the upper cover body 104 is slightly larger than that of the upper part of the upper cover 100, so that the upper cover body 104 can completely cover the built-in part 200 and the lower cover 300, one circle of first hooks 102 at the non-free end of the upper cover body 104 inside the upper cover 100 is matched with one circle of second hooks 304 on the main body of the lower cover 300, the limiting groove 203 is positioned on the outer surface of the built-in part 200 far away from the second slope surfaces 201, which is matched with the stopper 302 positioned at the lower edge of the inside of the body of the lower cover 300, and the stopper groove 203 is inserted into the stopper 302 after the built-in part 200 descends.

The working principle of the reservoir type bottle cap of the invention is as follows: under normal conditions, the accommodating chamber contains the substance to be mixed into the liquid, when the upper cover 100 is reversely screwed, the second slope surfaces 201 can be regarded as a right triangle, when long-edge movement occurs, the upper cover 100 can move downwards, so that the two first slope surfaces 101 of the upper cover 100 and the two second slope surfaces 201 of the built-in part 200 are mutually inosculated, the built-in part 200 can be pushed downwards by the upper cover 100 when being inosculated, the sealing film of the lower cover 300 can be pierced in the process that the built-in part 200 pushes downwards, and the substance to be mixed in the accommodating chamber can be mixed into the liquid of the bottle. Meanwhile, the limit groove 203 of the built-in part 200 is inserted into the limit block 302 of the lower cover 300, so that the built-in part 200 and the lower cover 300 are locked, and the first hook 102 of the upper cover 100 is held below the second hook 304 of the lower cover 300, so that the upper cover and the lower cover can be connected together. Then, the consumer rotates the upper cap 100 in the forward direction, since the built-in part 200 and the lower cap 300 are locked, and the upward movement of the upper cap 100 is restricted by the second hook 304 of the lower cap 300, the upper cap 100, the built-in part 200 and the lower cap 300 become an integral body during the forward rotation, so that the integral part consisting of the upper cap 100, the built-in part 200 and the lower cap 300 can be opened at the same time.

Further, the first slope surface 101 and the second slope surface 201 have concave-convex undulations, so that the first slope surface 101 on the upper cover 100 can be prevented from being separated from the corresponding second slope surface 201 on the built-in component 200 when the upper cover 100 is deformed under a force.

Further, the upper cover 100 further comprises an upper cover sealing ring 103, which is located on the inner upper surface of the upper cover 100 and forms an interference design with the inner wall of the built-in part 200 to realize mechanical sealing.

Further, the vertical direction of the higher side of the slope surface of the second slope surface 201 of the built-in part 200 includes a locking fin 202, the cover opening upper edge of the lower cover 300 includes a locking groove 301, the locking fin 202 and the locking groove 301 are matched with each other, and before the built-in part 200 descends, the built-in part 200 can be prevented from rotating along with the upper cover 100 when being screwed in the reverse direction. The locking fin can ensure that the built-in part 200 and the lower cover 300 are kept relatively immovable when being screwed down.

Furthermore, the sealing film comprises a tearing line, the tearing line avoids the central point, and the tearing can be immediately caused when the puncture needle contacts the film, but stress is accumulated and later torn, so that the tearing efficiency is improved.

Furthermore, the central spike column 204 is provided with at least two V-shaped grooves 2041, which can prevent the substance in the accommodating chamber from falling into the bottle when the sealing film is in close contact with the central spike column 204; meanwhile, after puncture, a channel for the air pressure in the accommodating chamber and the bottle can be provided.

Further, the central spike 204 has at least two rib portions 2042 for contacting and pressing down the sealing film after the sealing film is punctured, so as to expand the tearing area and simultaneously improve the strength of the central spike 204.

By adopting the reservoir type bottle cap of the invention, the diameter of the upper cap body 104 is slightly larger than that of the upper part of the upper cap 100, so that the upper cap body 104 can completely cover the cap built-in part 200 and the lower cap 300, and thus, when a consumer twists the bottle cap, only the outer surface of the upper cap 100 contacts fingers, so that the consumer does not need to select to twist the upper cap or twist the lower cap, the error of twisting the wrong upper cap or twisting the wrong lower cap is avoided, and the situation that substances in the storage chamber are scattered is avoided.

In addition, the invention adopts a reverse structure, a consumer firstly needs to reversely screw the bottle cap before drinking, so that the pre-stored powder or formula can fall into the bottle to be mixed with liquid, and the mixed beverage can be drunk after the consumer normally screws the bottle cap to open; if the consumer does not perform reverse screwing according to a normal procedure at first, but directly performs forward screwing, the steep surface of the first slope surface 101 contacts with the steep surface of the second slope surface 201, so that the lock fin 200 rotates along with the lock fin 100, and the lock fin 200 also contacts and interferes with the lock fin 300, so that the lock fin 300 also rotates along with the lock fin 200, and as a result, the whole bottle cap is opened, and the situation that the substances in the accommodating chamber are scattered outside the bottle is avoided. Meanwhile, the invention also provides a bottle comprising the reservoir type bottle cap.
