Description

Preserving container capable of removing residual gas

Technical Field

The utility model relates to a preservation container, in particular to a preservation container capable of exhausting residual air.

Background

Most of the food containers on the market are made of glass or Polypropylene (PP). As for glass materials, although this type of food container has good temperature resistance and washing resistance, the glass container is heavy and is easily broken when being impacted, and the plastic container made of polypropylene has light weight and is not easy to break, but the plastic container is easy to release substances harmful to human body or environment such as phenol methane (also called Bisphenol a, abbreviated as BPA), Polyvinyl Chloride (PVC) and plastic particles (microposts) during use, which causes consumer worry in using the current plastic container.

The applicant of the present application has been made to solve the above problems, and therefore, has made an effort to develop a food container made of silica gel. The silica gel material is refined from natural ore, has the characteristics of high temperature resistance and the like, is not easy to release toxicity and heavy metal when the container is used for containing food, and can eliminate the uneasiness of consumers in use. In addition, the material of the silica gel material has good fatigue resistance and is not easy to deform after long-term use.

On the other hand, the containers are currently modified to maintain the freshness of the food inside. For example, the US 8,783,490 patent discloses a sealing ring additionally disposed at the joint of the cover and the box, and the sealing ring is made of rubber, but is made of a different material than the food container, so the sealing ring must be additionally installed in the manufacturing process of the food container. More importantly, this type of container can only restrict the external air from entering the container, but the residual air existing inside the container cannot be discharged, so that the food stored in the container still contacts the residual air to affect the food.

Further, although US 2019/0119011 discloses that when the lid assembly is pressed against the body, the gas in the inner volume of the body is separated through the gap between the lid assembly and the body, it can be seen from a detailed reading that the lip of the lid assembly is pressed against the inner sidewall surface of the body during the process of combining the lid assembly and the body, so that the residual gas in the body is limited by the lip and cannot be discharged. In other words, the US 2019/0119011 patent actually can only exhaust the gas outside the lip, and cannot provide the technical teaching of exhausting the residual gas inside the body. Therefore, the container of this type still cannot solve the problem that the food is easily bred with bacteria and the freshness of the food is affected by the contact of the food stored in the container with the residual air.

SUMMERY OF THE UTILITY MODEL

The utility model mainly aims to solve the problem that residual air cannot be exhausted from a conventional storage container.

The present invention provides a storage container capable of exhausting residual air, comprising a first member and a second member, wherein the first member has a choke ring and a tongue piece formed on the choke ring and extending obliquely towards a direction away from the first member, the second member is selectively assembled with the first member to form a storage space, and the second member has a choke ring set matched with the choke ring. The gas blocking ring group and the gas blocking ring are combined to define an independent space, the tongue piece is positioned in the independent space, and the tongue piece is provided with a first state that the tail end is abutted against the second part to limit external gas to enter the holding space through the independent space and a second state that when residual gas in the storage space is pressed or attracted to enter the independent space, the tongue piece deforms to allow the residual gas to be discharged.

In one embodiment, the first member and the second member are silicone members.

In one embodiment, the choke ring set has an inner ring and an outer ring spaced apart from the inner ring.

In one embodiment, the outer ring is formed with a hook for hooking the edge of the first member.

In one embodiment, the air blocking ring is formed with at least one air guiding notch at one side facing the storage space.

In one embodiment, the air guiding notch is formed at the corner of the air blocking ring.

Through the implementation of the utility model, compared with the prior art, the utility model has the following characteristics: the tongue piece is arranged in the independent space, so that the tongue piece can keep the airtight state of the storage container when not pressed, and is deformed under the pressure of residual air in the storage space to allow the residual air to be discharged, thereby reducing the contact between food in the storage space and air.

Detailed Description

The present invention is described in detail and technical content with reference to the accompanying drawings, wherein:

referring to fig. 1 to 5, the present invention provides a storage container 100 capable of removing residual air, the storage container 100 includes a first part 10 and a second part 30, the first part 10 and the second part 30 are a cover and a box of the storage container 100, the first part 10 and the second part 30 can be selectively assembled to form a storage space 11, and the storage space 11 is used for placing a food (not shown) therein. Furthermore, the first member 10 and the second member 30 can be made of a silicone material, so as to reduce the release of toxic substances when the food is contained in the storage space 11.

Referring to fig. 1 to 5 again, for convenience of description, the first component 10 is taken as the box and the second component 30 is taken as the cover. The first member 10 has a choke ring 12 and a tongue piece 13, the choke ring 12 is located at the edge of the opening of the case and surrounds the storage space 11, and the tongue piece 13 is formed on the choke ring 12 and extends away from the first member 10. The second member 30 is provided with a choke ring set 31 on a side facing the first member 10, and the choke ring set 31 is located on the outer edge of the cover and is engaged with the choke ring 12. The choke ring set 31 and the choke ring 12 are combined to define an independent space 311, and the independent space 311 is located at the outer edge of the storage container 100 and is communicated with the storage space 11. It is worth noting that. Although the independent space 311 is connected to the storage space 11, the independent space 311 does not provide the food storage but provides the tongue piece 13 therein.

Referring to fig. 2 and 3, the tongue 13 has a first state in which a tip thereof abuts against the second member 30, and a second state in which the tongue itself deforms when the residual air in the storage space 11 is compressed or sucked into the independent space 311. To explain in detail, referring to fig. 2, it is assumed that the first member 10 and the second member 30 are not compressed initially, and the residual air in the independent space 311 is not sucked. At this time, the gas pressures at the two sides of the tongue piece 13 in the independent space 311 are balanced, the tongue piece 13 is not deformed and the end thereof is pressed against the second member 30, the tongue piece 13 is in the first state, and the external air is restricted from entering the storage space 11 through the independent space 311, so that the storage container 100 can be kept airtight. In the present embodiment, at least one of the first member 10 and the second member 30 is pressed to cause the residual air in the storage space 11 to flow to the independent space 311, at this time, the air pressure of the tongue piece 13 facing the storage space 11 is greater than the air pressure of the tongue piece 13 away from the storage space 11, so that the tongue piece 13 deforms and is transformed into the second state, the tongue piece 13 no longer abuts against the second member 30 in the second state, and the residual air is allowed to be discharged outside through the independent space 311 (as shown in fig. 3 by reference numeral 70), thereby reducing the possibility that the residual air of the storage container 100 remains in the storage space 11 and contacts with the food in the storage space 11.

Accordingly, the present invention provides the tongue piece 13 in the independent space 311, so that the tongue piece 13 can maintain the airtight state of the storage container 100 when not pressed, and can deform under the pressure of the residual air in the storage space to allow the residual air to be discharged, thereby reducing the contact between the food in the storage space 11 and the air to maintain the freshness of the food.

Referring to fig. 1 to 5, in an embodiment of the utility model, in order to assist the exhaust of the residual air, at least one air guiding notch 121 is formed on one side of the choke ring 12 facing the storage space 11, the air guiding notch 121 may be located at a corner of the choke ring 12 or at the other edge of the choke ring 12, and the air guiding notch 121 communicates the storage space 11 and the independent space 311 to guide the residual air in the storage space 11 to flow into the independent space 311 when being pressed or sucked. In addition, the choke ring set 31 of the present invention has an inner ring 312 and an outer ring 313, for example, the second member 30 is used as the cover, the choke ring set 31 is formed by the cover, the inner ring 312 is disposed at a position of the cover facing the storage space 11, and the inner ring 312 is not tightly attached to the wall surface of the choke ring 12 facing one side of the storage space 11, so that a gap exists between the inner ring 312 and the choke ring 12, and the residual air in the storage space 11 can flow into the independent space 311. The outer ring 313 is spaced apart from the inner ring 312, and the outer ring 313 contacts the outer edge of the case. Further, referring to fig. 4, the outer ring 313 is formed with a hook 314, a length of the hook 314 is determined by a thickness of an edge of the first component 10, the hook 314 hooks the edge of the first component 10 when the tongue 13 is in the first state, so that the second component 30 can be stably assembled with the first component 10, the hook 314 does not contact the first component 10 when the tongue 13 is in the second state, so that the air in the independent space 311 can flow out, as shown by reference numeral 70 in fig. 5.

In another embodiment, the first component 10 is configured to improve the structural strength, the first component 10 has an inner layer 14 and an outer layer 15 disposed outside the inner layer 14, the outer layer 15 assists to increase the strength of the inner layer 14, and a plurality of hollow areas 151 are formed, and the hollow areas 151 provide a portion of the inner layer 14 to be exposed, so that the thickness of the first component 10 can be changed.
