Description

Technical Field

[0001] This utility model relates to the field of food preservation technology, and in particular to a food preservation vacuum bag. Background Technology

[0002] Preservation means keeping food fresh, including preservation during storage, transportation, and sales. Generally, preservation refers to the storage and preservation of vegetables and fruits. For home use, vacuum-sealed food bags can be used to preserve food. Simply place the food inside the bag and use the included vacuum sealer to evacuate the inside, which helps extend the shelf life.

[0003] Vacuum-sealed food storage bags remove air from the bag through vacuuming. A vacuuming end is located on the bag body; a handheld vacuum pump is connected to this end to perform the vacuuming process. However, these vacuuming ends are typically not protected, and during movement, they can be damaged by impacts, leading to incomplete connection with the vacuum pump.

[0004] In view of this, we propose a food preservation vacuum bag. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a food preservation vacuum bag to solve the technical problem that the end of the vacuum is not protected and is prone to incomplete docking with the vacuum device after the end is damaged by collision.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a fresh-keeping vacuum bag, including a vacuum bag body, three sides of the vacuum bag body are heat-sealed, the opening end of the vacuum bag body is a bag mouth, a sealing strip is arranged at the bag mouth, and a vacuuming structure is also included.

[0007] A vacuuming structure is arranged on the vacuum bag body;

[0008] The vacuuming structure includes a vacuuming end, a cap, and a collar;

[0009] The vacuum end is arranged on the vacuum bag body;

[0010] The vacuuming end is connected to the inner cavity of the vacuum bag;

[0011] The cap is placed on the connecting end of the vacuuming end;

[0012] The collar is fitted onto the cover;

[0013] The collar is fitted and mated with the vacuuming end.

[0014] Preferably, the inner wall of the collar is fixed with a plurality of rubber blocks in a ring array, and the rubber blocks abut against the outer wall of the vacuum end.

[0015] Preferably, there is a gap between the inner wall of the collar and the outer wall of the vacuuming end.

[0016] Preferably, the rubber block has a hemispherical structure, and the spherical surface of the rubber block abuts against the outer wall of the vacuuming end.

[0017] Preferably, the outer ring wall of the collar is fixed with a plurality of protrusions in a ring array.

[0018] Preferably, a gap is provided between each pair of protrusions.

[0019] Preferably, the protruding end of the protruding block is trapezoidal, and the narrow end of the protruding end of the protruding block faces outward.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This utility model, by setting a cap and a collar, has the advantage of sealing the connection end of the vacuuming end by fitting a cap and a collar on the vacuuming end, thereby blocking and protecting the interface of the connection end of the vacuuming end, and solving the problem that the connection with the vacuum device is incomplete after the end is damaged by collision.

[0022] 2. This utility model has the advantage of positioning by setting a rubber block, which abuts against the outer wall of the vacuum pump end, making it easy to install and disassemble.

[0023] 3. By setting up protruding blocks, this utility model has the advantage that when holding the ring, the friction between the fingers and the protruding blocks is greater, making it less likely to slip off. Attached Figure Description

[0030] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0031] Example 1: A vacuum preservation bag, see [link / reference] Figures 1 to 3 ;

[0032] It includes a vacuum bag body 1, three sides of which are heat-sealed edges 2, the open end of the vacuum bag body 1 is a bag mouth 3, a sealing strip 4 is arranged at the bag mouth 3, the sealing strip 4 seals the bag mouth 3, and also includes a vacuuming structure 5.

[0033] A vacuuming structure 5 is arranged on the vacuum bag body 1; wherein, the vacuuming structure 5 includes a vacuuming end 501, a cap 502 and a collar 503; the vacuuming end 501 is arranged on the vacuum bag body 1; wherein, the vacuuming end 501 is connected to the inner cavity of the vacuum bag body 1; the cap 502 is placed on the mating end of the vacuuming end 501; the collar 503 is sleeved on the cap 502; wherein, the collar 503 is fitted and matched with the mating end of the vacuuming end 501.

[0034] This utility model, by setting a cover 502 and a collar 503, has the advantage of sealing the docking end of the vacuuming end 501 by covering the cover 502 and the collar 503 at the vacuuming end 501, thereby blocking and protecting the interface of the docking end of the vacuuming end 501, and solving the problem that the end is prone to incomplete docking with the vacuum device after being damaged by collision.

[0035] Example 2: A vacuum preservation bag, see [link / reference] Figure 3 and Figure 4 ;

[0036] There is a gap between the inner wall of the collar 503 and the outer wall of the vacuum end 501, which provides space for the rubber block 504 to enter without affecting the entry of the rubber block 504. Several rubber blocks 504 are fixed in a ring array on the inner wall of the collar 503, and the rubber blocks 504 abut against the outer wall of the vacuum end 501. The rubber blocks 504 are designed with a hemispherical structure, and the spherical surface of the rubber block 504 abuts against the outer wall of the vacuum end 501. The spherical surface of the rubber block 504 is not easily blocked and does not affect the compression of the rubber block 504.

[0037] This utility model has the advantage of setting a rubber block 504, which can be positioned by abutting the vacuum end 501 against the outer wall of the docking end, thereby fixing the collar 503 and facilitating installation and disassembly.

[0038] Example 3: A food preservation vacuum bag, see [link / reference] Figure 3 and Figure 4 ;

[0039] The outer ring wall of the collar 503 is fixed with several protrusions 505 in a ring array; there is a gap between each pair of protrusions 505; the protruding end of the protrusion 505 is set in a trapezoidal shape, with the narrow end of the protrusion 505 facing outward. The flesh at the finger is inserted into the gap between each pair of protrusions 505 to form a trapezoidal shape, making the compression more stable.

[0040] By setting up the protrusion 505, this utility model has the advantage that when holding the collar 503, the friction force of the fingers contacting the protrusion 505 is greater and it is not easy to slip off.

[0041] Working principle: Using the device of this utility model, the cap 502 is placed on the docking end of the vacuum end 501, and the collar 503 is fitted onto the docking end of the vacuum end 501. The spherical surface of the rubber block 504 abuts against the outer wall of the docking end of the vacuum end 501, and the collar 503 and the cap 502 are positioned with the docking end of the vacuum end 501. In use, the collar 503 and the cap 502 are removed, and the built-in vacuum pump is connected to the vacuum end 501 to draw a vacuum.

[0042] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
