technical field

The utility model relates to a bottle cap used in conjunction with a bottle body, a bottle and a mold device for molding the bottle cap.

Background technique

Bottle caps are very common in daily life. Various bottles such as beverage bottles, health care bottles and medicine bottles will be sealed with bottle caps.

At present, most of the beverage bottles on the market are single-layer knob bottle caps with single function, and the bottle caps only play a sealing role simply. There are also a small number of storage bottle caps, such as medicine bottle caps, which have an openable upper storage cavity and a lower joint for engaging the bottle body. The upper part of the upper storage cavity has a snap-fit The small cap, like this, the user can place some items such as some kind of medicine that is taken in conjunction with the medicine in the bottle in the storage cavity. When the user needs to take the medicine, the user can buckle the small cap to open the storage cavity and take it out medicine, unscrew the bottle cap, take out another medicine from the bottle, and take it together. These aforementioned bottle caps each have certain characteristics/advantages, which bring certain convenience to people's lives.

On the other hand, with the improvement of people's living standards, there are higher requirements and awareness for the quality of drinks, product shelf life and the use of product additives.

Therefore, the used directional terms are used to illustrate but not to limit the present invention. In addition, the same reference numerals refer to the same elements in all embodiments.

Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

At first, with reference to Fig. 1-4, describe the bottle and bottle cap according to a preferred embodiment of the present invention, wherein, Fig. 1 is to show the sectional view of described bottle according to this embodiment; Fig. 2 is as shown in Fig. 1 Figure 3 shows the bottle cap part of the bottle in Figure 1 alone; Figure 4 shows the bottle body part of the bottle in Figure 1 alone.

As shown in FIG. 1 , the bottle according to the aforementioned preferred embodiment comprises a cap 10 and a body 20 which are fitted together for use (by screwing in this embodiment).

Further, as shown in Figure 3, the bottle cap 10 includes a storage part 101 (generally including the part shown by the upper dotted line box) located on the upper part of the bottle cap 10 for containing materials, and the storage parts 101 are connected to each other by The top 1011, the side wall 1012 and the bottom 1013 are formed into a closed hollow shell. It should be noted that in the accompanying drawings of the present utility model, for the sake of brevity, the materials contained in the storage part 101 are not shown, but when the bottle cap is used together with the bottle body, the bottle cap is usually stored There is material, which is loaded before the storage portion is sealed, as will be described in more detail later. The bottle cap 10 also includes an engaging portion 102 extending downward from the bottom 1013 of the storage portion 101 for engaging with the bottle body 20 , so that the bottle cap 10 can be screwed onto the bottle body 20 . The structure of the engaging portion 102 may be the same as or similar to that of the side wall portion with helical teeth of the knob bottle cap in the prior art.

As shown more clearly in FIG. 2, a breakable structure is formed on the bottom 1013 of the storage portion 101. The split part 10131, preferably, the breakable part 10131 can be formed as an annular weak part on the bottom 1013 of the storage part that is thinner than other parts of the bottom. The breakable part 10131 is designed to be broken under the action of the upward force of the top end 201 of the bottle mouth of the bottle after the bottle cap is screwed down relative to the bottle body and travels beyond a predetermined position, so as to form a The position of the breakable part is separated from the bottom 1013 of the storage part (the falling part is the part with a diameter d1 shown in FIG. 3 ), so that the inside of the storage part It communicates with the inside of the bottle so that the material can enter the bottle. Thus, the preferred bottle cap according to this embodiment can be used in the following situations:

Solvent such as pure water is stored in the bottle body 20, and then the bottle cap 10 is capped, and like this, the bottom 1013 of the storage part 101 of the bottle cap 10 and the joint part 102 of the bottle cap 10 both function as a conventional knob cap. function, the solvent can be sealed in the bottle; further, the materials to be mixed with the solvent, such as dry vitamin tablets, can be stored in the storage part 101 (note: about how to implement the material into the storage Part 101, which will be described later), since the storage part 101 itself forms a closed space, the materials can be stored for a long time without being polluted. In this way, the separation and storage of the solute and the solvent are realized, which is beneficial to improving the shelf life of each. When a user such as a consumer is ready to drink a beverage, he/she can screw down the bottle cap so that the top 201 of the bottle mouth of the bottle pushes against the bottom 1013 of the bottle cap, and under the action of the upper force, the bottom 1013 of the bottle cap Break from the breakable part 10131 to form the aforementioned disengagement part, the disengagement part leaves the bottom 1013 of the bottle cap and actually makes the bottom 1013 form an opening, like this, the material in the storage part 101 will fall into the bottle body, and the solvent will For mixing, of course, the bottle can also be turned upside down, so that the solvent in the bottle body enters the bottle cap to mix with the material. In this way, consumers can make fresh and delicious drinks on the spot through the usual twisting and shaking actions.

The aforementioned bottle/bottle cap according to the present utility model has at least one or more or all of the following advantages:

First, since the materials and solvents are stored separately and sealed separately, it is possible to increase the shelf life. For example, if the solvent is purified water, long-term shelf life can be achieved without adding any preservatives. In contrast, for traditional mixed beverages, it may be difficult to achieve long shelf life without adding preservatives due to the nourishment contained in the beverage.

Second, the method for users to mix materials and solvents is extremely simple, just through the usual steps of screwing the bottle cap and shaking the bottle body. These actions conform to people's consistent usage habits and provide the possibility for the product to have a good market.

Thirdly, the structure of the cap itself is very simple and the manufacturing cost is low, which provides the possibility to produce caps/bottles/beverages with competitive price.

Fourth, since the disengagement part is detached from the bottom of the bottle cap, the material and the solvent can be fully contacted and mixed. Compared with, for example, using a sharp object to puncture an opening at the bottom for mixing, the mixing is more efficient. Easy and homogeneous, this offers the possibility to prepare beverages with a good mouthfeel.

Fifth, the mixing of materials and solvents is carried out in a fully enclosed environment, which can provide a more hygienic drink compared to the traditional mixing method such as opening the bottle cap and pouring materials.

Sixth, the bottle cap of the present invention uses the existing/necessary top of the bottle mouth instead of introducing new parts/parts to break through the bottom of the storage part. It has ingenious design, simple structure, high reliability and low cost.

It should be pointed out that for the convenience of description, the above is described with the mixing of solid materials and liquid solvents, but the bottle cap of the present invention is not limited to the separation/mixing of solid/liquid, and can also be applied to solid/solid, Liquid/liquid separation/mixing where both solid and liquid can be stored in the cap and both solid and liquid can be stored in the bottle body. In addition, in this paper, for the convenience of description, the expression of bottle cap/bottle body is used to describe the bottle. In fact, in some cases, for example, the bottle cap is larger and the bottle body is smaller. At this time, due to the The cap has storage function, in fact the bottle cap can also be called the bottle body, and the bottle body is called the bottle cap. The expression bottle cap/bottle body itself does not constitute a limitation to the protection scope of the present utility model, and in some cases, the expression bottle cap and bottle body can be used interchangeably.

In addition, it should be noted that, in the present utility model, "rupturable part" refers to a part that can be broken, specifically, after the bottle cap is screwed down relative to the bottle body and travels beyond a predetermined position, the bottle The top of the bottle mouth of the body is against the bottom of the storage part, and under the action of the upward force, the part that can be broken. Under this concept, the "rupturable part" can be realized through various means in the prior art, such as making the rupturable part weaker than its surrounding parts. As long as the above-mentioned "rupturable part" can be broken under the action of the upward force at the top of the bottle mouth, the design falls within the scope of the present invention.

The following continues to describe the structure of the bottle cap according to the preferred embodiment of the present invention. In a preferred embodiment according to the present utility model, the rupturable part 10131 can be formed at a position opposite to the top of the bottle mouth of the bottle body. The radially outer position, more preferably, the rupturable portion is formed at a position opposite to the outer wall of the top end of the bottle mouth of the bottle, as shown in FIG. The diameter d1 of the detachment part will be greater than the inner diameter of the bottle mouth and will not fall into the bottle body. In this way, when the consumer mixes the material and the solvent, no "foreign matter" (ie the detachment part) will enter the bottle body, giving People have a bad feeling/illusion that the beverage is contaminated by foreign matter, although even if the detachment part enters the bottle body, it will not pollute the beverage, because the detachment part itself meets the corresponding hygienic standards. Further preferably, in any of the above-mentioned embodiments of the present utility model, the area of the bottom 1013 of the storage part is larger than the area of the shedding part, that is, the diameter d2 of the bottom of the storage part shown in the figure is larger than The diameter d1 of the disengagement part is more conducive to preventing, for example, that the disengagement part is disengaged from the bottom when the diameter d2 is equal to the diameter d1, but in some cases it still blocks the mixing of the material and the solvent in the bottle.

Further, in a preferred embodiment according to the present utility model, as shown in FIG. 2 , the joint part 102 may include a screwing part 1021 which is screwed with the bottle mouth of the bottle body and is integrated downward from the screwing part 1021 Extended limiting portion 1022 . The limiting part 1022 is designed to abut against the protruding part 202 on the outer wall of the bottle mouth of the bottle body after the bottle cap is screwed to seal the bottle so that the bottle cap cannot move further downwards. On the other hand, the limiting part 1022 is disengaged from the screwing part after being torn by the user, so that the bottle cap 10 can be screwed down and travel beyond a predetermined position, so that the bottle mouth moves upward relative to the bottle cap, breaking the aforementioned rupturable Part 10131, so that the disengagement part is disengaged. In this way, if the user does not tear off the limiting portion 1022 , the bottle cap cannot be screwed down, thereby preventing the user from accidentally screwing down the bottle cap and causing the rupturable portion to break and undesirably mix the material and the solvent. As for the specific structure of the limiting part, it can be formed as a ring belt that is common in traditional bottle cap design to restrict the bottle cap from being unscrewed. However, in the utility model, the main function of the limiting part/other One effect is to prevent the bottle cap from being screwed down.

Below Figures 5 and 6, describe how to manufacture the bottle cap shown in Figure 3, wherein Figure 5 shows a part of the bottle cap made by a mold, and Figure 6 shows another part of the bottle cap made by another mold part. Since the bottle cap according to the embodiment of the present utility model has an airtight storage part 10, and the storage part 10 needs to be filled with materials, therefore, the inventor thought of dividing the bottle cap into The two parts are manufactured separately, and then, for example, materials are placed in a container as shown in FIG. 5 , and then the part shown in FIG. 5 is combined with the part shown in FIG. 6 .

Specifically, since the bottle caps are usually made of plastic, the bottle caps can be molded by a mould. In particular, a mold can be used which has a cavity corresponding to the shape of the top 1011 and side wall 1012 of the storage part of the bottle cap, whereby the top 1011 and side wall 1012 of the storage part can be molded as One. On the other hand, another mold can be utilized, which has a mold cavity corresponding to the shape of the bottom 1013 of the bottle cap and the joint part 102, whereby the bottom 1013 of the storage part and the bottle cap can be combined with the bottle mouth. The screw fit joint 102 is molded in one piece. Then, the material is packed in the storage part, for example, in the container of the opening of the storage part as shown in FIG. together, such as by ultrasonic welding, to form a storage portion sealed with material. It can be understood that for the final finished bottle cap, the entire bottle cap is an integral part. Here, it should be noted that the side wall portion 1012 and the joint portion 102 shown in FIGS. 1-3 have a separation surface, and they are formed into two parts in terms of drawing rules, but this is only for description and drawing For the convenience of the finished bottle cap, the two are actually integrated, not two parts.

In the aforementioned process of manufacturing the bottle cap, as shown in Figure 5, the top of the bottle cap can be made to have a transparent part 10111, so that the material inside the storage part can be seen from the outside, so that the user can confirm the quality of the material. state. Preferably, the transparent part 10111 is formed by a thinner part in the center of the top than the surrounding part. In this way, since the bottle cap is usually made of plastic, the thin part naturally forms the transparent part. Cover materials.
