Description

High-temperature sterilization silica gel valve pressure regulating bottle cap

Technical Field

The utility model belongs to the technical field of bottle lid equipment, specific saying relates to a high temperature sterilization silica gel valve pressure adjustment bottle lid.

Background

At present, most of milk products and protein beverages are pasteurized, and the method has the defects that the shelf life is as short as 7 to 14 days, and the milk products and the protein beverages are not easy to store and transport and sell in a long distance. The shelf life of the product can be prolonged only by high-temperature sterilization, and the shelf life of the product after high-temperature sterilization can reach 180 days or even longer.

However, the existing bottles for containing milk products are easy to crack and other accidents because the liquid in the bottles expands at high temperature,

there is therefore a need for improvements to existing closures.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems existing in the prior art, the utility model provides a high-temperature sterilization silica gel valve pressure adjusting bottle cap.

The technical scheme of the utility model is realized like this:

the utility model provides a high temperature sterilization silica gel valve pressure regulation bottle lid, is including being used for the lid with the bottleneck butt joint of bottle, the internal surface of lid is equipped with the screw thread that is used for the fastening, the through-hole is seted up at the top of lid, the through-hole diameter is less than the lid diameter, it has the elastic membrane to bond on the outer wall of through-hole, the elastic membrane is sunken to the bottleneck in.

Further, the elastic membrane is bonded with the outer wall of the through hole.

Further, the elastic membrane is made of food-grade silica gel materials.

Further, the elastic membrane is in an inverted conical shape.

The utility model discloses an operating principle's effect as follows:

the cover body of the scheme can be matched with a common PP bottle body on the market, and the cover body can be put into a high-temperature sterilization pot for sterilization by screwing the cover body through the screw thread for fastening arranged on the inner surface of the cover body; the through-hole is seted up at the top of lid, the through-hole diameter is less than lid diameter, it has the elastic membrane to bond on the outer wall of through-hole, the elastic membrane is sunken in to the bottleneck, and when pasteurization, liquid takes place to expand because of high temperature in the bottle, to body and lid generate pressure, and the elastic membrane atress of silica gel material is outwards expanded and is not damaged through lid top through-hole this moment to liquid in the bottle has been alleviated to the pressure of body and lid, has played the effect of protection body and lid.

After the sterilization is finished, the volume of the liquid in the bottle body is reduced along with the reduction of the temperature to the normal temperature, and the shape and the position of the elastic membrane are restored.

The scheme can thoroughly sterilize at high temperature, avoids bottle body breakage and is low in cost.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

In addition, the descriptions related to "first", "second", etc. in the present invention are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit ly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

Example 1

As shown in fig. 1-2, the pressure regulating bottle cap with the high-temperature sterilization silica gel valve comprises a cap body 2 which is used for being in butt joint with a bottle opening at the top of a bottle body 1, wherein threads 3 for fastening are arranged on the inner surface of the cap body 2, a through hole 4 is formed in the top of the cap body 2, the diameter of the through hole 4 is smaller than that of the cap body 2, an elastic membrane 5 is bonded on the outer wall of the through hole 4, and the elastic membrane 5 is sunken towards the bottle opening.

The elastic membrane 5 is adhered to the outer wall of the through hole 4.

The elastic membrane 5 is made of food-grade silica gel material.

The elastic membrane 5 is in the shape of an inverted cone.

When in specific use:

the cover body 2 of the scheme can be matched with a common PP bottle body 1 on the market, and the cover body 2 can be put into a high-temperature sterilization pot for sterilization by screwing the cover body 2 through the screw thread 3 for fastening arranged on the inner surface of the cover body 2; through-hole 4 is seted up at the top of lid 2, through-hole 4 diameter is less than 2 diameters of lid, it has elastic membrane 5 to bond on the outer wall of through-hole 4, elastic membrane 5 is inwards sunken to the bottleneck, and when pasteurization, liquid takes place to expand because of high temperature in the bottle, to body 1 and lid 2 generate pressure, and 5 atresss of elastic membrane of silica gel material are outwards expanded and not damaged through lid 2 top through-hole 4 this moment to liquid in the bottle to body 1 and lid 2's pressure has been alleviated, has played the effect of protection body 1 and lid 2.

After the sterilization is finished, the liquid volume in the bottle body 1 is reduced along with the reduction of the temperature to the normal temperature, and the shape and the position of the elastic membrane 5 are restored.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
