Abstract
Description
Technical Field:
[0001] The utility model relates to the technical field of packaging bag sealing structures, and more specifically to a self-sealing structure and a medical cotton swab packaging bag using this structure. Background Art:
[0002] Medical cotton swabs are commonly used consumables in departments. Currently, cotton swabs are all placed in plastic bags, and the plastic bag mouth is provided with a mother-child embedded strip-shaped sealing strip that is sealed by manual pinching. Once manually pinched, it can prevent the cotton swabs from being contaminated, but there are also obvious problems. First, the sealing strip is soft. When pinching, generally one hand needs to hold the corner of the bag, and the two fingers of the other hand gradually pinch the entire sealing strip. When opening, one hand cannot operate independently either. Both hands must hold one side of the upper edge of the bag and pull it outward to separate the sealing strip; to a certain extent, it affects the efficiency. More importantly, if one hand needs to perform aseptic operation, it is not convenient to repeatedly touch the packaging bag. Second, the currently manually pinched sealing strip cannot be immediately sealed after the cotton swabs are taken out. The reason is that when doctors and nurses are treating patients, if they take out the cotton swabs and then pinch the sealing strip of the cotton swab bag at the same time, it will increase the exposure time of the cotton swabs outside the bag. Moreover, once the cotton swabs come into contact with the patient, they cannot be dipped in disinfectant again, so the cotton swabs must be replaced, and the pinched sealing strip will increase the time for taking the cotton swabs again.
[0003] In a home environment operation, when dealing with some minor wounds, the above problems are not prominent. However, when the use environment is a hospital where higher efficiency and aseptic requirements are needed, improving the above problems will be very helpful for clinical practice. Summary of the Utility Model:
[0004] To solve the above problems and overcome the deficiencies of the prior art, the utility model intends to provide a self-sealing structure that can be opened with one hand and automatically and immediately closed and sealed, and a medical cotton swab packaging bag using this structure.
[0005] To achieve the above purpose, the self-sealing structure provided by the utility model includes two symmetrically arranged elastic pieces. The elastic piece ends of the two elastic pieces are fixedly connected. The middle parts of the two elastic pieces are convex arc-shaped structures, and a soft sealing pad is fixedly connected to the middle parts of the elastic pieces respectively.
[0006] Further, the side of the soft sealing pad fixedly connected to the elastic piece is an arc-shaped that fits the inner wall of the elastic piece. The other side of the soft sealing pad includes a parallel upper plane and a lower plane. The upper plane is a vertical plane, and the lower plane is concave and forms a stepped structure with the upper plane.
[0007] Further, an adhesive layer is provided on the surface of the lower plane, and a removable protective layer is provided outside the adhesive layer.
[0008] Furthermore, a pressing cushion block is fixedly connected to the end of the elastic sheet.
[0009] A medical cotton swab packaging bag using the above self-sealing structure further includes a bag body. The outer surfaces on both sides of the upper part of the bag body are fixedly connected to the lower planes of two soft sealing gaskets through adhesive stickers respectively.
[0010] Furthermore, the thickness of the single layer of the bag body is adapted to the height difference between the lower plane and the upper plane.
[0011] The beneficial effects of the present utility model are as follows: The present utility model provides a self-sealing structure that can be opened with one hand and automatically and immediately closed and sealed. Through the arrangement of the elastic sheet, it is ensured that when the external force disappears, the elastic sheet restores its original shape through its own elastic force, and then automatically presses the two soft sealing gaskets tightly together to play a sealing role; and the middle part of the elastic sheet is designed into a convex arc structure, which ensures that when an external force is applied inward from the end of the elastic sheet, the two elastic sheets always move in a direction of separating from each other, and then the state where the two soft sealing gaskets are tightly attached together is released, so that the middle parts of the two soft sealing gaskets are in a pituitary-shaped opening.
[0012] The bag body of the medical cotton swab packaging bag using the above self-sealing structure is made of a soft material, and the upper part is an open mouth. The outer surfaces on both sides of the upper part of the bag body are adhered to the self-sealing structure through the adhesive stickers on the lower plane of the soft sealing gasket. Since the lower plane is concave and forms a stepped structure with the upper plane, the adhesion of the bag body to the self-sealing structure will not affect the sealing performance.

[0019] To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be described in more detail below in conjunction with the accompanying drawings of the present utility model.
[0020] In the description of the present utility model, it should be understood that the description of the orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the protection scope of the present utility model.
[0021] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0022] Among them, the elastic piece is also called an elastic sheet or a spring piece, and is a sheet-shaped elastic member that can return to its original shape through its own elastic force after being deformed by an external force.
[0023] As shown in the attached Figures 1-4 figure, the self-sealing structure includes two symmetrically arranged elastic pieces 1. The elastic ends 101 of the two elastic pieces 1 are fixedly connected. The middle parts 102 of the two elastic pieces 1 are outwardly convex arc-shaped structures, and a soft sealing pad 2 is fixedly connected to each of the middle parts 102 of the elastic pieces 1.
[0024] One side of the soft sealing pad 2 fixedly connected to the elastic piece 1 is an arc-shaped that fits the inner wall of the elastic piece 1. The other side of the soft sealing pad 2 includes a parallel upper plane and a lower plane. The upper plane is a vertical plane, and the lower plane is concave and forms a stepped structure with the upper plane.
[0025] The surface of the lower plane is provided with an adhesive layer, and a removable protective layer is provided outside the adhesive layer.
[0026] A pressing pad is fixedly connected to the elastic end 101.
[0027] The self-sealing structure provided by the utility model includes two symmetrically arranged elastic pieces 1, which are automatically sealed by utilizing the characteristic that the elastic pieces 1 automatically return to their initial shapes when the external force disappears; the ends of the two elastic pieces 1 are fixedly connected to ensure that the elastic pieces 1 do not separate from each other. The middle parts 102 of the two elastic pieces are outwardly convex arc-shaped structures. The outward convex arc ensures that when an external force is applied, the two elastic pieces 1 do not bend on the same side or squeeze each other inward, but always move in a direction of separating from each other.
[0028] In order for the soft sealing gasket 2 to have a good sealing effect, the other side of the soft sealing gasket 2 includes an upper plane and a lower plane that are parallel to each other. The upper plane is a vertical plane. The soft sealing gasket 2 fixedly connected to the middle part 102 of the elastic piece is squeezed under the elastic force of the elastic piece 1 to play a sealing role.
[0029] In order to cooperate with the bag body 4 of the packaging bag, the lower plane of the soft sealing gasket 2 is concave and forms a stepped structure with the upper plane. An adhesive layer is provided on the surface of the lower plane, and a removable protective layer is provided outside the adhesive layer. It can be fixedly connected to the bag body 4 through the adhesive layer. Such a design makes the sealing structure have a wider application range. It can be combined and produced during the production of the packaging bag, and can also be used as a component for all soft bags that need to be sealed.
[0030] In order to make the pressing easier and the fingers not feel pain due to frequent pressing in a short time, pressing pads are fixedly connected to the ends of both ends of the elastic piece 1. The pressing block can be a rubber cap with a larger contact area or a hard structure to reduce the pressure directly acting on the fingers.
[0031] As shown in the appendix Figure 5 A medical cotton swab packaging bag using the above self-sealing structure further includes a bag body 4. The outer surfaces on both sides of the upper part of the bag body 4 are fixedly connected to the lower planes of the two soft sealing gaskets 2 through adhesives respectively. The thickness of a single layer of the bag body 4 is adapted to the height difference between the lower plane and the upper plane.
[0032] The outer surfaces on both sides of the upper part of the packaging bag body 4 are fixedly connected to the lower planes of the two soft sealing gaskets 2 through adhesives respectively. The thickness of a single layer of the bag body 4 is adapted to the height difference between the lower plane and the upper plane; the width of the bag body 4 is less than the length of the soft sealing gasket 2, which can ensure convenient access to the contents in the bag body 4 and quick automatic sealing after use, avoiding being contaminated by exposure to the air for a long time.
[0033] The utility model provides a self-sealing sealing structure which can be opened with one hand and automatically and instantly closed and sealed. The arrangement of the spring sheet 1 ensures that when the external force disappears, the spring sheet 1 restores its original shape through its own elastic force, thereby automatically and tightly fitting the two soft sealing pads 2 together to achieve a sealing effect. The middle portion 102 of the spring sheet is designed to be an outwardly convex arc structure, thereby ensuring that when an external force is applied inward from the end portion 101 of the spring sheet, the two spring sheets 1 always move in a directional manner to separate from each other, thereby releasing the state in which the two soft sealing pads 2 are tightly fitted together, so that the middle portions of the two soft sealing pads 2 present an opening 3 in the shape of a hypostyle.
[0034] The bag body 4 of the medical cotton swab packaging bag using the above-mentioned self-sealing sealing structure is made of soft material and is open at the top. The outer surfaces on both sides of the upper part of the bag body 4 are adhered to the self-sealing sealing structure through the adhesive of the lower plane of the soft sealing pad 2. Since the lower plane is concave and has a step-shaped structure with the upper plane, the bag body 4 will not affect the sealing after being adhered to the self-sealing sealing structure.
[0035] Except for the technical features described in the specification, all other technical features are known to those skilled in the art.
