Description

Bottle cap and packaging bottle

Technical Field

The invention belongs to the technical field of storage, and relates to a bottle, in particular to a bottle cap.

The invention belongs to the technical field of storage, and relates to a bottle, in particular to a packaging bottle.

Background

The bottle cap is used for sealing the bottle. The operation method for opening the bottle cap is various, for example, the mineral water bottle cap is opened by screwing; the pop can cap is opened by tearing the pull ring; the lid of the beer bottle is opened by prying the lid edge.

The applicant has proposed a preserving bottle (No. CN 204096269U) and a preserving bottle cap (No. CN 105173355B) with an inner bag, which can store seasonings such as soy sauce and vinegar in the preserving bottle, and the cavity of the inner bag is reduced after part of the seasonings are squeezed out. Although the bottle cap is provided with the one-way device, air is prevented from entering the inner bag, the possibility that the seasoning is contacted with the air is reduced, the flavor of the seasoning is further kept, and the quality guarantee period of the seasoning is prolonged; however, the bottle has the defects that when the bottle is pinched, the one-way device of the bottle cap can be suddenly opened and the seasoning can be sprayed out, so that the discharging mode is acceptable when the seasoning is put into the pot; when a condiment is placed in a dip dish, the sprayed condiment often spills, and may then spill onto clothing, dishes, and/or table tops, creating unnecessary stains and wasting condiment. It would therefore be desirable to provide a bottle cap suitable for dispensing condiment from a package into a dipping dish.

Disclosure of Invention

The invention provides a bottle cap, and the technical problem to be solved by the invention is how to make the bottle cap with a one-way device suitable for dispensing condiment in a packaging bottle into a dipping dish.

The technical problem to be solved by the invention can be realized by the following technical scheme: a bottle cap comprises a connecting seat, wherein a discharge hole is formed in the top wall of the connecting seat, a partition plate and a one-way cap are arranged in the connecting seat, the outer edge part of the partition plate is fixedly connected with the connecting seat in a sealing mode, and the one-way cap is located between the partition plate and the top wall of the connecting seat; an annular sealing surface area is arranged in the upper plate surface of the partition plate, a material passing hole is formed in the partition plate, and an orifice of the material passing hole is positioned on the inner side of the sealing surface area; the one-way cap is connected with the connecting seat or the partition plate through a connecting structure which enables the outer edge part of the one-way cap to abut against the sealing surface area of the partition plate, and when the outer edge part of the one-way cap abuts against the sealing surface area of the partition plate, sealing is formed between the one-way cap and the partition plate.

The materials of the one-way cap and the connecting seat are selected to ensure that the one-way cap and the partition plate form sealing when the outer edge part of the one-way cap abuts against the sealing surface area of the partition plate, namely the discharge hole is not communicated with the material passing hole. The one-way cap enables the cavity between the top wall and the partition plate to form a circuitous flow passage, the area, located on the inner side of the one-way cap, in the cavity between the top wall and the partition plate is called a first cavity, the area, located on the outer side of the one-way cap is called a second cavity, and the content can flow from the first cavity to the second cavity only by jacking up the sealing structure of the one-way cap and the partition plate.

When people invert the bottle and pinch the bottle, the pressure in the bottle rises, the content in the bottle firstly enters the cavity between the top wall and the partition plate from the material passing hole, particularly, the content can flow into the first cavity from the material passing hole in a spray shape, and the content is sprayed on one side surface of the one-way cap; when the pressure of the first chamber rises and the sealing structure of the one-way cap and the partition is pushed open, the contents flow into the second chamber from the gap between the outer edge portion of the one-way cap and the sealing surface area of the partition. Finally, the contents are discharged from the discharge hole to a holding container; because the acting force is usually applied for a short time when people pinch the bottle every time and the acting force applied by pinching the bottle is limited, the flow and the pressure of the contents are obviously reduced under the structural action of the bottle cap, so that the contents flowing out of the discharge hole are usually in a drop shape; even if the force is applied for too much and/or for too long, the content can continuously flow out of the discharge hole, the pressure of the content is extremely low, and the content cannot form a spray shape, so that the content cannot splash after colliding with the dipping dish.

When people stop pressing the bottle, the outer edge part of the one-way cap abuts against the sealing surface area of the partition plate under the action of negative pressure in the inner cavity of the bottle and/or under the action of elastic force, and the outer edge part of the one-way cap and the sealing surface area of the partition plate form sealing, so that air is prevented from flowing back into the bottle.

Compared with the prior art, the bottle cap can reduce the flow of the content and the pressure of the content by controlling the size of the material passing hole. The one-way cap in the bottle cap is not plugged in the material passing hole, but a sealing surface formed between the one-way cap and the partition plate is positioned outside the material passing hole, so that the material passing hole is opposite to one side surface of the one-way cap; the content impacts on the one-way cap, the one-way cap and the partition plate are pushed open by the content, and the circuitous flow of the content can effectively reduce the flow rate of the content and the pressure of the content. Through the flow and the pressure of multistage reduction content for the content pressure and the flow that flow from the discharge gate is all less, and the distribution is to dipping in the dish in the time the content can not splash.

A kind of packing bottle, including bottle and above-mentioned bottle cap, the bottle has body to accommodate the content and bottleneck for the content to discharge, the wall of the connecting seat is fixedly connected with bottleneck in the bottle cap hermetically; the bottle body comprises a deformable outer shell and a flexible inner bag, the inner bag is positioned in the outer shell, and the material passing hole is communicated with an inner cavity of the inner bag; the outer shell is provided with an air flow control structure which only enables air to flow into a cavity between the outer shell and the inner bag from the outside.

When people pinch the bottle body, the bottle body deforms and the inner cavity is reduced, the air flow control structure prevents air in the cavity between the outer shell and the inner bag from leaking out, and therefore the air pressure in the cavity between the outer shell and the inner bag is increased; and then the inner bag is extruded to force the content in the inner bag to flow out from the discharge hole of the bottle cap. This structure further reduces the pressure to which the inner bag is subjected, thereby reducing the possibility of the contents flowing out in a spray pattern.

When people stop pressurizing the bottle, the air flow control structure enables air to flow into a cavity between the outer shell and the inner bag from the outside, and the bottle body is deformed and reset; the cap forms a seal that prevents air from flowing back into the inner bag.
