Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical packaging bags, and in particular to a medical sterilization self-sealing packaging bag. Background Art
[0002] Usually, hospitals will store patients' test items or some items used by medical staff in sterilized self-sealing bags, so the sealing effect of the self-sealing bags is particularly important. Self-sealing bags include sterilization paper and composite film. After the sterilization paper and composite film are attached together, a U-shaped heat seal strip is pressed out by mechanical equipment. After the items are placed in the bag, the opening of the U-shaped heat seal strip is sealed with double-sided tape.
[0003] In the related art, a strong double-sided adhesive tape is attached to the inner wall of the sterilization paper near the opening of the U-shaped heat seal strip (the side near the composite film). When sealing the opening of the packaging bag, it is only necessary to tear off the double-sided adhesive tape and stick it on the composite film. However, when the packaging bag needs to be torn open, the double-sided adhesive tape has a strong adhesion and has no tear line, making it difficult to tear open the packaging bag. Utility Model Content
[0004] In order to improve the convenience of tearing open a self-sealing packaging bag, the present application provides a medical sterilization self-sealing packaging bag.
[0005] The present application provides a medical sterilization self-sealing packaging bag, which adopts the following technical solution:

[0007] In order to facilitate tearing off the sealing paper strip from the composite film, an easy-to-tear gap is provided between the double-sided adhesive tape and the end of the heat sealing strip facing away from the sterilization paper.
[0008] In order to facilitate tearing off the sealing paper strip from the sterilization paper, a partition gap is provided between the double-sided adhesive tape and the breakable line.
[0009] In order to prevent the double-sided adhesive tape from sticking to the composite film when the packaging bag is not in use, a non-stick film is attached to the double-sided adhesive tape.
[0010] In order to facilitate tearing off the non-stick film from the double-sided adhesive when using the packaging bag, both opposite ends of the non-stick film protrude from the sterilization paper.
[0011] In order to improve the sealing performance of the U-shaped heat sealing strip on the peripheral side of the packaging bag, a plurality of U-shaped heat sealing strips are provided, and the plurality of U-shaped heat sealing strips are mutually nested and arranged at intervals.
[0012] In order to prevent the U-shaped heat sealing strip from being damaged by direct impact on the article after it is placed in the placement cavity, a buffer heat sealing strip is arranged at the bottom of the groove of the innermost U-shaped heat sealing strip.
[0013] In order to improve the sealing performance of the sealing paper strip on the bag opening, a tape foot is provided on the side of the double-sided tape close to the easy-to-break line to increase the sealing of the bag opening.

[0017] 1. When sealing the mouth of the packaging bag, fold the sealing paper strip, make the sealing paper strip buckle on the composite film and make the sealing paper strip stick to the composite film through the double-sided tape. If the packaging bag needs to be torn open, the operator only needs to open the partition gap of the sealing paper strip by hand and then make the sealing paper strip break from the easy-to-break line and be torn off;
[0018] 2. When not using the packaging bag, just stick the non-stick film on the double-sided tape so that the double-sided tape does not stick to the composite film;
[0019] 3. The arrangement of multiple U-shaped heat sealing strips enables the packaging bag to be multi-sealed except for the surrounding side of the bag opening. Even if one of the U-shaped heat sealing strips loses its sealing effect, the remaining U-shaped heat sealing strips can still play a sealing role, thereby improving the sealing effect of the packaging bag.

[0023] The following is combined with Figure 1-2 This application is described in further detail.
[0024] The present application embodiment discloses a medical sterilization self-sealing packaging bag. Figure 1 and Figure 2 The medical sterilization self-sealing packaging bag includes a sterilization paper 1 and a composite film 2, which are heat-sealed together by a heat-sealing device to form a bag with a placement cavity. A U-shaped heat-sealing strip 21 is formed between the sterilization paper 1 and the composite film 2 by a heat-sealing device, and the opening of the U-shaped heat-sealing strip 21 is assumed to be the bag opening. A sealing paper strip 11 is provided at one end of the sterilization paper 1 close to the bag opening, and a breakable line 12 is provided between the sealing paper strip 11 and the sterilization paper 1, and the sealing paper strip 11 can be folded and pasted on the side of the composite film 2 away from the sterilization paper 1 to seal the bag opening. When the bag opening is torn open, under the action of the breakable line 12, the sealing paper strip 11 is more easily disconnected from the sterilization paper 1 to allow the bag opening to be opened.
[0025] Reference Figure 1 and Figure 2 The composite film 2 is a rectangular and transparent film, which makes it easy to see the inside of the bag. A transparent card pocket 22 is integrally formed on the side of the composite film 2 away from the sterilization paper 1. Medical staff can write the information of the items in the packaging bag on a card and then insert the card into the card pocket 22, which makes it easy for others to understand the information of the items in the packaging bag.
[0026] There are multiple U-shaped heat sealing strips 21 formed by hot pressing. The sizes of the multiple U-shaped heat sealing strips 21 are different, but the opening directions of the multiple U-shaped heat sealing strips 21 are consistent. The multiple U-shaped heat sealing strips 21 are nested together and arranged at equal intervals, thereby forming multiple seals on the packaging bag, thereby improving the sealing effect inside the packaging bag.
[0027] Reference Figure 1 and Figure 2 When an item is put into the packaging bag from the bag opening, the item will automatically move away from the bag opening under the action of gravity and impact the U-shaped heat seal strip 21. If the impact force is large, the U-shaped heat seal strip 21 will be easily broken open. Therefore, a buffer heat seal strip 23 is hot-pressed between the sterilization paper 1 and the composite film 2. The buffer heat seal strip 23 is located in the innermost U-shaped heat seal strip 21, and the buffer heat seal strip 23 is located on the side away from the bag opening. After the item is put into the packaging bag, it will directly impact the buffer heat seal strip 23 under the action of gravity. The buffer heat seal strip 23 can remove part of the impact force, so that the impact force of the item is not easy to directly act on the U-shaped heat seal strip 21.
[0028] Reference Figure 1 and Figure 2The side of the sealing paper strip 11 close to the composite film 2 is affixed with a double-sided adhesive tape 13, and when the sealing paper strip 11 is folded, it can be attached to the composite film 2 through the double-sided adhesive tape 13. There is an easy-tear gap between the side of the sealing paper strip 11 away from the easy-tear line 12 and the double-sided adhesive tape 13, and the sealing paper strip 11 at the easy-tear gap cannot be attached to the composite film 2, and it is easier to uncover the sealing paper strip 11 when tearing it off.
[0029] There is a partition gap between the double-sided tape 13 and the fragile line 12. The partition gap makes it difficult for the sealing paper strip 11 to stick to the sterilization paper 1 at the sealing paper strip 11, making it easier for the sealing paper strip 11 to break at the fragile line 12 when it is torn off.
[0030] Reference Figure 1 and Figure 2 In addition, in order to improve the sealing performance at the bag opening after the sealing paper strip 11 is folded and attached to the composite film 2, two tape legs 14 are integrally formed on the side of the double-sided adhesive tape 13 close to the easy-to-break line 12. The two tape legs 14 are arranged at intervals, and the two tape legs 14 are respectively located at the two ends of the outer side of the opening of the innermost U-shaped heat sealing strip 21. In this way, the partition gap of the sealing paper strip 11 can be attached to the sterilization paper 1 to improve the sealing performance. At the same time, since the area of the tape legs 14 is small, it does not affect the breaking of the sealing paper strip 11 from the easy-to-break line 12.
[0031] Reference Figure 1 and Figure 2 The side of the double-sided adhesive tape 13 facing away from the sealing paper strip 11 is pasted with a non-stick film 15, which is an oily film and is not easy to have a large stickiness with the double-sided adhesive tape 13. The double-sided adhesive tape 13 can be shielded by the non-stick film 15, so that the double-sided adhesive tape 13 is not easy to stick to other objects when not sealed. The opposite ends of the non-stick film 15 protrude from the sterilization paper 1, making it more convenient to tear off the non-stick film 15. Since two tape legs 14 are also provided on the side of the double-sided adhesive tape 13 close to the easy-to-break line 12, a convex piece that shields the tape legs 14 is also integrally formed at the corresponding position on the non-stick film 15.
[0032] The implementation principle of a medical sterilization self-sealing packaging bag in the embodiment of the present application is: first, when sealing the bag mouth, tear off the non-stick film 15, then fold the sealing paper strip 11 so that the sealing paper strip 11 is buckled on the composite film 2 and the sealing paper strip 11 is attached to the composite film 2 through the double-sided tape 13.
[0033] When opening the packaging bag, the operator only needs to open the partition gap of the sealing paper strip 11 with his hands and then tear off the sealing paper strip 11 from the fragile line 12, and the whole process is relatively convenient.
[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
