Description

Technical Field

[0001] This utility model relates to the field of medical product packaging technology, and in particular to an anti-adhesion dressing encapsulation body. Background Technology

[0002] In the prior art, products such as adhesive bandages, dressings, and medical patches that are sheet-like and coated with adhesive are packaged using release paper and / or release film to cover the entire adhesive area in order to prevent the adhesive from sticking to the packaging material and making it impossible to peel the product off.

[0003] However, in practical applications, taking hydrocolloid dressings as an example, due to the inherent adhesive properties of the hydrocolloid matrix, even with complete coverage using release paper, there is still a certain probability of leakage at the edges, leading to adhesion to the packaging material. Meanwhile, ordinary sterile dressings and other similar dressing products consume a large amount of release paper during use. The disposal of this used release paper not only increases production costs but also generates significant amounts of medical waste. Furthermore, release paper suffers from poor transparency; during production, workers cannot directly observe the adhesive surface of the product through the release paper, potentially allowing contaminated or substandard products to enter the market, posing a potential risk of medical accidents. Utility Model Content

[0004] The purpose of this invention is to provide an anti-adhesion adhesive packaging body to alleviate the technical problems existing in the prior art where packaging materials stick to the product, generate a large amount of medical waste, and make it impossible to directly observe the surface contamination of the product when using release paper and / or release film packaging.

[0005] This utility model provides an anti-adhesion dressing package, which includes a dressing body and an outer packaging;

[0006] The dressing body includes a base layer and an adhesive layer coated on one side of the base layer;

[0007] The outer packaging is formed by combining a first encapsulation layer and a second encapsulation layer. An encapsulation space is formed between the first encapsulation layer and the second encapsulation layer via a sealing portion, and the adhesive body is encapsulated within the encapsulation space.

[0008] A first release agent layer is coated on one side of the first encapsulation layer facing the encapsulation space; the coating area of ​​the first release agent layer is not smaller than the projection area of ​​the adhesive layer, and the adhesive layer of the adhesive body is adhered to the first release agent layer.

[0009] Furthermore, the shape of the first release agent layer is the same as the shape of the base layer; the coating area of ​​the first release agent layer is smaller than the area of ​​the first encapsulation layer.

[0010] Further, the first encapsulation layer is a transparent film.

[0011] Further, a second release agent layer is coated on the side of the second encapsulation layer facing the encapsulation space;

[0012] The second release agent layer has a shape of a ring overlapping the outer periphery of the first release agent layer.

[0013] Further, the outer edges of any one side of the first encapsulation layer and the second encapsulation layer extend to form a tear opening.

[0014] Further, the two corner edges of the end of the edge sealing part facing the tear opening are rounded.

[0015] Further, the edge line of the end of the edge sealing part facing the tear opening protrudes to form a pointed end part.

[0016] Advantages:

[0017] The utility model provides a kind of anti-adhesion plaster encapsulation, including plaster body and outer package, and plaster body includes base layer and adhesive layer coated on the side surface of base layer;Outer package is formed by the combination of first encapsulation layer and second encapsulation layer, and encapsulation space is formed between first encapsulation layer and second encapsulation layer via edge sealing part, and plaster body is encapsulated in encapsulation space;

[0018] By adopting the method of combining one layer of visible packaging layer and one layer of sterilization paper packaging layer, an encapsulation space that is neither breathable nor water-permeable is constructed, the plaster body is placed therein, and then ethylene oxide is used for sterilization treatment.In shelf life, bacteria will not breed in the cavity, and it can be directly observed from the outside whether the internal plaster core part or adhesive layer is contaminated.In addition, due to visualization, contaminated products can be detected and removed in time on the production line, and medical staff can also directly discard them if they find mold breeding or dirt before use, effectively preventing medical accidents.

[0019] A first release agent layer is coated on the side of the first encapsulation layer facing the encapsulation space;The coating area of the first release agent layer is not less than the projection area of the adhesive layer, and the adhesive layer of the plaster body is pasted on the first release agent layer.Using release agent to cover the adhesive layer instead of release paper and / or release film can also prevent the plaster from adhering to the outer package;At the same time of saving cost and reducing medical waste, the plaster product and the encapsulation structure can be integrated by directly pasting the adhesive layer and the release agent on the outer package, so as to avoid displacement and falling during transportation and storage.And when it is needed to use, the outer package can be torn open, and the plaster base layer can be directly taken off from the first encapsulation layer, which is very convenient.In addition, the release agent on the surface of the packaging material can also reduce the size of the outer package, thereby reducing the packaging cost, warehousing and logistics cost and sterilization cost.BRIEF DESCRIPTION OF DRAWINGS BRIEF DESCRIPTION OF DRAWINGS

[0036] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] Embodiment 1

[0038] As Figure 1 , Figure 2As shown, the utility model embodiment 1 provides a kind of anti-adhesion application packaging body, including application body 1 and outer package 2, application body 1 includes base layer 101 and adhesive layer 102 coated on the side surface of base layer 101;

[0039] Optionally, according to the different kinds of application body 1, can be provided with application core (such as conventional dressing material) at the center of adhesive layer 102, or also can not be provided with application core (such as hydrocolloid dressing material, and in this case, the layer for directly adhering to living body formed by the material such as hydrocolloid of dressing material is adhesive layer 102 in the utility model).

[0040] Outer package 2 is formed by the combination of first packaging layer 201 and second packaging layer 202, and the packaging space is formed between first packaging layer 201 and second packaging layer 202 via edge portion 203, and application body 1 is packaged in the packaging space;

[0041] First release agent layer 3 is coated on the side of first packaging layer 201 facing the packaging space; the coating area of first release agent layer 3 is not less than the projection area of adhesive layer 102, and adhesive layer 102 of application body 1 is pasted on first release agent layer 3.

[0042] Specifically, the first packaging layer 201 and the application body 1 are adhered together through the first release agent layer 3 and the adhesive layer 102; the second packaging layer 202 is the same size as the first packaging layer 201 and is aligned and stacked together, and the edge portion 203 is formed by heat melting or pressing around the surface of the first packaging layer 201 and the second packaging layer 202; after the application body 1 is placed in the packaging space and sterilized by passing through ethylene oxide, it can ensure that no bacteria grow in the cavity within the shelf life, and due to the transparency and visibility, the application core part (the middle black square area) on the application body 1 or the adhesive layer 102 can be clearly observed on the first packaging layer 201. Figure 1 In addition, visualization can detect and remove contaminated products online, and medical staff can discard them once they find mold growth or dirt before use, to avoid medical accidents.

[0043] Adhesive layer 102 is coated on application body 1, and base layer 101 of application body 1 is adhered to the side of first packaging layer 201 coated with first release agent layer 3 through adhesive layer 102; the coating area of first release agent layer 3 is not less than adhesive layer 102, so that first release agent layer 3 can cover the area of adhesive layer 102; precisely positioning application body 1 on the first release agent layer 3 on the surface of the packaging material can also reduce the size of outer package 2, thereby reducing packaging cost, warehousing and logistics cost and sterilization cost.

[0044] The first encapsulation layer 201 is a transparent film. Preferably, the first encapsulation layer 201 can be a composite film of PE+PET, a composite film of CPP+PET, a PET film or other transparent films, which can be directly observed whether the patch body 1 is contaminated or discolored through the transparent first encapsulation layer 201 without setting a large piece of release paper / film. The material of the second encapsulation layer 202 is not particularly limited, and is preferably sterilized paper. The sterilized paper is not air and water permeable, but can permeate ethylene oxide. The patch body 1 can be sterilized by ethylene oxide, which can ensure that no bacteria grow in the packaging structure of the outer package 2 within the shelf life after sterilization, thereby achieving a sterile environment.

[0045] Specifically, the coating area of the first release agent layer 3 is smaller than the area of the first encapsulation layer 201, i.e. not covering the entire first encapsulation layer 201, preventing the position of the first release agent layer 3 from covering the entire first encapsulation layer 201, which will make the first encapsulation layer 201 and the second encapsulation layer 202 unable to be heat sealed.

[0046] By coating the first release agent layer 3 on the first encapsulation layer 201 for the adhesive layer 102 to adhere, one or two large pieces of release paper / film that need to be adhered to the adhesive layer 102 can be saved, which can greatly save costs and reduce the generation of medical waste. In addition, the patch body 1 and the first encapsulation layer 201 can be integrated by directly adhering the adhesive layer 102 to the first encapsulation layer 201, so that the patch body 1 will not shift and fall off during transportation and storage, avoiding material overflow and sticking to the package. Furthermore, when needed, the outer package 2 is torn open, and the patch body 1 is directly torn off from the first encapsulation layer 201, which is convenient to operate.

[0047] Specifically, the shape of the first release agent layer 3 is the same as that of the base layer 101. The shape of the base layer 101 is not limited to rectangular, rounded rectangular, circular, but can also be oval or waist round, etc. According to the actual situation of the patch body 1, the shape of the first release agent layer 3 can be changed accordingly, so that the outer package 2 can be used for more shapes of patch body 1.

[0048] It should be noted that the edge portion 203 has at least one side not sealed along the outer periphery on the first encapsulation layer 201 and the second encapsulation layer 202, i.e. when the outer package 2 is torn open, one side of the product packaging structure can be torn open by separating the first encapsulation layer 201 and the second encapsulation layer 202.

[0049] It should be noted that the base layer 101 is taken out of the outer package 2, adhered to the user's skin by the adhesive layer 102, and then peeled off from the user's skin. Therefore, the base layer 101 is a network-like structure sheet composed of fibers or a film-like sheet formed of a thermoplastic material.

[0050] It should be noted that the edge sealing part 203 is in a heat sealing form to seal the first packaging layer 201 and the second packaging layer 202, and the heat sealing temperature is 100-230 DEG C, and the time is 1-8 s. The adhesion of the first packaging layer 201 and the second packaging layer 202 under the heat sealing temperature and time conditions can ensure the strength, stability and safety of the packaging structure of the outer package 2.

[0051] Embodiment 2

[0052] In the embodiment 2 of the utility model, as shown in Figure 3 、 Figure 4 The second release agent layer 4 is coated on one side of the second packaging layer 202 facing the packaging space, and the shape of the second release agent layer 4 is annular, that is, it can be a square ring, a circular ring, an oval ring or a circular rectangular ring, which overlaps the outer periphery of the first release agent layer 3.

[0053] Specifically, when facing the application body 1 such as hydrocolloid dressing, silicone gel foam dressing or transparent dressing (PU transparent breathable film) and the like (such products usually do not have a dressing core), it is found that in the actual use process, due to the material problem of the adhesive layer 102, it is extremely likely to cause edge overflow phenomenon during transportation and storage, and once such overflow phenomenon occurs, the application body 1 and the lower second packaging layer 202 will be adhered. Further, when trying to separate the first packaging layer 201 and the second packaging layer 202, the application body 1 is damaged or the second packaging layer 202 is damaged and left on the application body 1, causing great inconvenience.

[0054] Therefore, in the embodiment, the first release agent layer 3 is coated on the first packaging layer 201, and the coating area of the first release agent layer 3 is larger than the area of the adhesive layer 102; and the second release agent layer 4 with the same outer periphery as the first release agent layer 3 is coated on the second packaging layer 202, so that even if the overflow phenomenon occurs, the overflowed glue will be blocked by the first release agent layer 3 and the second release agent layer 4, and will not contact the first packaging layer 201 or the second packaging layer 202. Thus, the application body 1 of the hydrocolloid type can be used without being affected by the overflow during packaging and storage.

[0055] It should be noted that, due to the different adhesion and material of the adhesive layer 102 on the application body 1, the first release agent layer 3 and the second release agent layer 4 include organic release agent or inorganic release agent. The release force of the first release agent layer 3 and the second release agent layer 4 is 3-60 g / 25 mm, and the release agent coating amount is 0.1-4 g / m 2 . 2 So that the application body 1 can be easily peeled off from the outer package 2.

[0056] Embodiment 3

[0057] In embodiment 3 of this utility model, a tear 5 is formed by extending the outer edge of either the first encapsulation layer 201 or the second encapsulation layer 202.

[0058] The two corners of the edge sealing part 203 facing the tear opening 5 are rounded chamfers 6.

[0059] Specifically, such as Figure 5 As shown, since the first packaging layer 201 and the second packaging layer 202 are fused together, if the size of the unsealed area is too small, the outer packaging 2 may not be able to be torn open or the two may not be easy to separate. Since the two are the same length, it is not convenient to pinch them. Therefore, either side of the first packaging layer 201 and the second packaging layer 202 is extended forward to realize a packaging layer tear 5 with one long and one short, which makes it easy to pinch and separate the two packaging layers at the same time.

[0060] Specifically, when separating the first encapsulation layer 201 and the second encapsulation layer 202 through the tear 5, if the sealing edge 203 is a right angle, the force will be concentrated at the vertex of the right angle when tearing, which can easily cause the material of the first encapsulation layer 201 or the second encapsulation layer 202 to tear, resulting in the inability to open the encapsulation structure. However, by setting the rounded chamfer 6, the force area can be distributed to facilitate tearing the outer packaging 2 and avoid tearing the material.

[0061] Example 4

[0062] In Embodiment 4 of this utility model, the edge sealing portion 203 protrudes from the edge line of one end toward the tear opening 5 to form a pointed portion 7. Compared with Embodiment 3, the only difference in Embodiment 4 is that the shape of the edge sealing portion 203 has been changed.

[0063] Specifically, such as Figure 6 As shown, when separating the first packaging layer 201 and the second packaging layer 202 from the tear 5, the first layer contacts the tip 7, and the entire tearing force is applied to the tip 7, making it easier to tear open the outer packaging 2.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
