A pre-cooked food storage container having a good seal

Abstract

The application provides a prefabricated food storage container with good sealing performance, and relates to the technical field of food storage, which comprises a mounting mechanism, a sealing performance detection structure composed of an airtight groove A, an airtight groove B, an end groove and a telescopic block, a piston and a screw structure in a top cover, and a negative pressure principle, which is used for directly detecting the sealing state of the container. When the container is well sealed, the telescopic block remains in a retracted state. Once a sealing gap occurs and the air pressure changes, the telescopic block will automatically extend, so that the user can directly judge the sealing failure and take timely remedial measures. The application solves the problem that the existing storage containers generally lack special structures for assisting in detecting the sealing performance, but after long-term use, a sealing gap is prone to occurring at the splicing position of the container body and the top cover, which causes external air, moisture or microorganisms to enter the container, thereby damaging the food storage environment. Since the application lacks the structure for assisting in detecting, the user cannot directly and quickly judge whether the container has a sealing failure problem.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food storage, in particular to a pre-prepared food storage container with good sealing performance. BACKGROUND

[0002] With the popularity of fast-paced lifestyle and the large-scale development of the food industry, pre-prepared food (covering categories such as instant heating, instant eating, instant cooking, etc.) has become an important food form in household consumption, catering retail and outdoor scenarios. The core needs of such food for storage containers in the production, circulation, terminal storage and consumption links revolve around freshness, safety, convenience and adaptability - both to delay the quality deterioration caused by food oxidation and microbial growth, and to meet the hygiene standards of food contact materials.

[0003] However, the existing pre-prepared food storage containers still have multi-dimensional technical pain points in actual application, which are difficult to fully match the upgrading needs of the market for food storage quality and use experience.

[0004] Firstly, the volume of the existing storage container is mostly fixed design, which cannot be flexibly adjusted according to the actual storage demand of pre-prepared food. When the amount of pre-prepared food to be stored by the user exceeds the fixed volume of a single container, multiple containers need to be used for sub-packaging, which may cause the food to be exposed to air for a longer time due to sub-packaging operation, increasing the risk of quality deterioration.

[0005] Secondly, the existing storage containers generally lack special structures for assisting in detecting sealing performance. The sealing performance of the storage container mainly depends on the splicing and fitting between the container body and the top cover. However, after long-term use, the splicing part of the container body and the top cover is prone to sealing gaps, which allows external air, moisture or microorganisms to enter the container, thereby destroying the food storage environment and causing food spoilage. Due to the lack of auxiliary detection structure, the user cannot intuitively and quickly determine whether the container has sealing failure problem, and can only realize it when the food quality is found to be abnormal, which makes it difficult to avoid the risk of food spoilage in advance and seriously affects the storage reliability. SUMMARY

[0006] In view of the above problems, one object of the present application is to overcome these shortcomings, and more specifically to provide a pre-prepared food storage container with good sealing performance, which can be easily adjusted according to the amount of pre-prepared dishes, thereby completing the storage of pre-prepared dishes at one time, and assisting in detecting the sealing performance between the storage container body and the top cover to ensure the sealing effect of the storage container.

[0007] The application discloses a prefabricated food storage container with good sealing performance.

[0008] Preferably, the mounting mechanism comprises: a movable groove, a pin plate, an inner lining and a bottom groove; the movable groove is arranged on the two sides of the main body and is located at the upper end of each side groove; the pin plate is slidably arranged in the movable groove, and the lower end of the pin plate can extend into the side groove; the inner lining is arranged in the main body; and the bottom groove is symmetrically arranged on the two sides of the bottom of the inner lining.

[0009] Preferably, the mounting mechanism comprises: airtight groove A and a sealing sheet; the airtight groove A is arranged in the inner wall on the two sides of the upper end of the main body, and the upper end airtight groove A is in communication with the end groove; and the sealing sheet is arranged in the airtight groove A when the two main bodies are spliced.

[0010] Preferably, the mounting mechanism comprises: a fixed plate and a matching groove; the fixed plate is arranged on the outer sides of the main body; and the matching groove is arranged at the middle position of the fixed plate.

[0011] Preferably, the movable mechanism comprises: a sealing block, a moving groove and a limiting groove; the sealing block is in a C-shaped structure; the moving groove is arranged at the middle position in the sealing block; and the limiting groove is arranged at the upper end of the sealing block.

[0012] Preferably, the movable mechanism comprises: a lifting block and a clamping groove; the lifting block is arranged on the inner side of the sealing block and is slidably connected with the moving groove through a spring; and the clamping groove is arranged in the lifting block and has a size matched with the fixed plate.

[0013] Preferably, the top mechanism comprises: a top cover and an inner groove; the top cover is in a rectangular structure; and the inner groove is arranged at the center position in the top cover.

[0014] Preferably, the top mechanism comprises: a communication groove and an air-tight groove B; the communication groove is arranged at the periphery of the inner groove; the air-tight groove B is arranged at the inner side of the lower end of the top cover, and the air-tight groove B is communicated with the communication groove.

[0015] Preferably, the top mechanism comprises: a piston and a screw rod; the piston is slidingly installed in the inner groove, and the piston can only move up and down in the inner groove; the screw rod is rotationally installed at the upper end of the inner side of the top cover, and the screw rod is threadedly connected with the piston, and when the screw rod is rotated, the piston moves in the inner groove.

[0016] Preferably, the top mechanism comprises: a turnover piece and a stopper; the turnover piece is rotationally installed at the two sides of the outer side of the top cover; the stopper is slidingly installed on the turnover piece through a spring.

[0017] The application provides a prefabricated food storage container with good sealing performance, which has the following beneficial effects:

[0018] 1. The sealing detection structure composed of the air-tight groove A, the air-tight groove B, the end groove and the telescopic block is arranged, and the piston and the screw rod structure in the top cover are matched, so that the sealing state of the container can be directly detected through the negative pressure principle. When the container is well sealed, the telescopic block remains in the retracted state. Once the sealing gap causes the air pressure to change, the telescopic block will automatically extend, so that the user can directly judge the sealing failure and take timely remedial measures, effectively avoiding the risk of food oxidation caused by poor sealing, and significantly improving the reliability and safety of prefabricated food storage.

[0019] 2. The main body structure and the matched sealing block, lifting block and other components are arranged, so that the rapid splicing and fixing of multiple container main bodies are realized.
