Description

Technical Field

[0001] This application relates to the field of packaging, and in particular to a semi-pull-out ear pad. Background Technology

[0002] In the production process of food, pharmaceuticals, and other products, the products can be filled into bottles for storage. In existing technologies, to reduce the impact of the external environment on the product, a gasket can be placed at the bottle opening, and the gasket is bonded and fixed to the bottle body. This gasket separates the product inside the bottle from the external environment, thereby reducing the impact of moisture, gases, and other substances in the external environment on the product inside the bottle.

[0003] Reference Figure 1 To facilitate separation of the gasket from the bottle, a tear-off piece can be provided on the upper part of the gasket body. The tear-off piece includes an adhesive part and a gripping part, with the adhesive part of the tear-off piece bonded and fixed to the gasket body. Thus, when the user needs to separate the gasket from the bottle body, the user squeezes the gripping part of the tear-off piece and moves the tear-off piece, thereby separating the gasket body from the bottle body.

[0004] However, when the user moves the tear strip, there is a situation where the adhesive part of the tear strip separates from the gasket body, while the gasket body remains bonded to the bottle body; thus, the user cannot effectively break the bottle opening. Utility Model Content

[0005] To facilitate the user's separation of the gasket from the bottle body, this application provides a half-pull-out gasket.

[0006] This application provides a semi-pull-out ear pad, which adopts the following technical solution: A semi-pull-out pad includes a pad body, a tear-off component, and a connector; the pad body is used to cover the bottle opening and is bonded to the bottle body; the tear-off component includes an adhesive portion and a gripping portion, the adhesive portion of the tear-off component being bonded to the pad body; the connector includes an integrally formed first component and a second component, the first component being bonded to the pad body and the second component being bonded to the gripping portion.

[0007] By adopting the above technical solution, a connector is set between the tear-off piece and the gasket body to improve the overall connection strength of the gasket; the tear-off piece, the connector and the gasket body have a large connection strength, thereby ensuring that the tear-off piece and the connector can carry the gasket body together to move, so that the gasket body can be separated from the bottle body; so that the user can separate the gasket from the bottle body and achieve the purpose of breaking the bottle opening.

[0008] Optionally, it may also include a friction element, which is fixed to the second component.

[0009] By adopting the above technical solution and setting a friction element on the second component, the friction between the user's hand and the pad can be increased when the user pinches the tearing part and the connecting part, so that the user can remove the pad.

[0010] Optionally, a turning crease line is provided between the adhesive part and the gripping part, and the gripping part is turned around the turning crease line; the second component is stacked on the first component.

[0011] By adopting the above technical solution, the second component is stacked on the first component, so that the friction plate is set between the first component and the second component, and the sealing plate has a separating effect on the first component and the second component, thereby making it easy for the user to separate the first component and the second component, and making it easy for the staff to pinch the second component and the pinching part.

[0012] Optionally, the friction coefficient of the friction element is greater than that of the connecting element and the tearing element.

[0013] By adopting the above technical solution, the friction coefficient of the friction component is greater than that of the connecting component, thereby increasing the friction between the user's hand and the pad, making it easier for the user to remove the pad.

[0014] Optionally, the friction element includes a plurality of anti-slip protrusions, which are spaced apart on the second component.

[0015] By adopting the above technical solution, several anti-slip protrusions are spaced apart on the second component, thereby increasing the friction between the user's hand and the pad, so that the user can remove the pad.

[0016] Optionally, the anti-slip ridges are arc-shaped, and several anti-slip ridges are spaced apart along the radial direction of the second component.

[0017] By adopting the above technical solution, several anti-slip ridges are spaced apart along the radial direction of the second component to increase the friction between the user's hand and the pad, so that the user can remove the pad.

[0018] Optionally, the gasket body includes a heat-sealing film layer, an aluminum foil layer, and a cardboard layer in sequence; the heat-sealing film layer is used to abut against the bottle body, the aluminum foil layer is used to receive electromagnetic waves and generate heat, and the aluminum foil layer is used to heat the heat-sealing film layer, so that the heat-sealing film layer melts and adheres to the bottle body.

[0019] By adopting the above technical solution, the aluminum foil layer is used to receive electromagnetic waves and generate heat, and the aluminum foil layer is used to heat the heat-sealing film layer. The heat-sealing film layer melts and adheres to the bottle body, thus facilitating the adhesion and fixation of the gasket to the bottle body.

[0020] Optionally, the gasket body further includes a barrier layer, which is fixed between the heat-sealing film layer and the aluminum foil layer; the barrier layer is used to prevent moisture and gas from entering the bottle.

[0021] By adopting the above technical solution, the barrier layer can play an additional barrier role, preventing gas, moisture and other substances from entering or escaping through the sealing gasket; thus maintaining the quality of the product inside the bottle.

[0027] The following is in conjunction with the appendix Figure 1 -3 provides further detailed description of this application.

[0028] This application discloses a semi-pull-out ear pad. (Refer to...) Figure 1 The half-pull ear gasket includes a gasket body 1, a tear-off piece 2, and a connector 3.

[0029] Reference Figure 1 The gasket body 1 is used to cover the bottle opening and is bonded to the bottle body. The gasket body 1 includes a heat-sealing film layer 11, a barrier layer 12, an aluminum foil layer 13, and a cardboard layer 14. The heat-sealing film layer 11 is used to abut against the bottle body, and the aluminum foil layer 13 is used to receive electromagnetic waves and generate heat. The aluminum foil layer 13 heats the heat-sealing film layer 11, causing it to melt and bond to the bottle body. The barrier layer 12 is fixed between the heat-sealing film layer 11 and the aluminum foil layer 13; the barrier layer 12 prevents moisture and gas from entering the bottle body.

[0030] Reference Figure 1 The barrier layer 12 is made of a high-barrier material, such as polyester (PET) or other plastic films. The barrier layer 12 provides additional barrier protection, preventing gases and moisture from entering or escaping through the sealing gasket, thus maintaining the quality of the product inside the bottle. The cardboard layer 14 can be made of PE foamed cardboard, giving it a certain degree of elastic compression deformation capability. Therefore, when the bottle cap presses down on the gasket, the elastic deformation of the cardboard layer 14 forces the heat-sealing film layer 11 to fit tightly against the bottle body.

[0031] Reference Figure 1 The tear-off piece 2 includes an adhesive portion 21 and a gripping portion 22. The adhesive portion 21 of the tear-off piece 2 is bonded and fixed to the gasket body 1. A turning crease line is provided between the adhesive portion 21 and the gripping portion 22, and the gripping portion 22 is turned around the turning crease line.

[0032] Reference Figure 1 The connector 3 includes an integrally formed first component 31 and a second component 32. The first component 31 is bonded and fixed to the gasket body 1, and the second component 32 is bonded and fixed to the gripping part 22. In this embodiment, the second component 32 and the gripping part 22 together form the pull tab of the gasket; the user grips the pull tab of the gasket to separate the gasket from the bottle body.

[0033] Reference Figure 1 In this embodiment, both the tear-off piece 2 and the connector 3 are membrane structures, which facilitates the bonding and fixing of the tear-off piece 2 and the connector 3 to the gasket body 1; and the tear-off piece 2 and the connector 3 have a certain structural strength. For example, the tear-off piece 2 and the connector 3 can be made of polytetrafluoroethylene material to give them a certain structural strength.

[0034] The implementation principle of a semi-pull-out ear pad in this application embodiment is as follows: Reference Figure 1 The staff placed the gasket at the bottle opening and tightened the bottle cap to the bottle body; this caused the bottle cap to press down on the gasket, the cardboard layer 14 in the gasket to be elastically compressed, and the hot air film layer in the gasket body 1 to be in close contact with the bottle body.

[0035] Subsequently, under the action of the electromagnetic field, the aluminum foil layer 13 heats up and transfers the heat to the barrier layer 12 and the heat-sealing film layer 11 in sequence. After the heat-sealing film layer 11 melts when heated, it adheres and fixes to the bottle body, thereby achieving a sealed connection between the gasket and the bottle body.

[0036] Reference Figure 1 When a user needs to break the bottle opening, the user squeezes the gripping part 22 of the tear-off piece 2 and the second part 32 of the connector 3, and moves the tear-off piece 2 and the connector 3. Since the adhesive part 21 of the gripping piece and the first part 31 of the connector 3 are both bonded and fixed to the gasket body 1, the overall connection strength of the gasket is improved. When the user moves the tear-off piece 2 and the connector 3, the tear-off piece 2 and the connector 3 have a large connection strength with the gasket body 1, thereby ensuring that the tear-off piece 2 and the connector 3 can carry the gasket body 1 along with it, so that the gasket body 1 can be separated from the bottle body.

[0037] Reference Figure 1 That is, by setting a connector 3 between the tear-off piece 2 and the gasket body 1, the overall connection strength of the gasket is improved; when the user moves the tear-off piece 2, the adhesive part 21 of the tear-off piece 2 is reduced from separating from the gasket body 1, while the gasket body 1 is still bonded and fixed to the bottle body; thus, it is convenient for the user to separate the gasket from the bottle body and achieve the purpose of breaking the bottle opening.

[0038] Example 2 The difference between Example 2 and Example 1 is as follows: Reference Figure 2 The gasket also includes a friction element, which is fixed on the second component 32, and the second component 32 is stacked on the first component 31. In this embodiment, the friction coefficient of the friction element is greater than that of the connecting component 3 and the tearing component 2. The friction element can be made of materials such as a frosted film 4 or rough paper. In this embodiment, the friction element can be a frosted film 4 to facilitate the user's gripping of the second component 32 and the gripping part 22.

[0039] The implementation principle of a semi-pull-out ear pad in this application embodiment is as follows: Reference Figure 2 The friction coefficient of the frosted film 4 is greater than that of the connector 3, thereby improving the user's grip on the second component 32 and the gripping part 22; it can increase the friction between the user's hand and the pad, so that the user can remove the pad.

[0040] Example 3 The difference between Example 3 and Example 1 is as follows: Reference Figure 3The friction element includes a plurality of anti-slip protrusions 5, which are spaced apart on the second component 32. In this embodiment, the anti-slip protrusions 5 are arc-shaped, and a plurality of anti-slip protrusions 5 are spaced apart along the radial direction of the second component 32. In this embodiment, the anti-slip protrusions 5 and the connecting component 3 are made of the same material, and the anti-slip protrusions 5 are bonded to the second component 32.

[0041] The implementation principle of a semi-pull-out ear pad in this application embodiment is as follows: Reference Figure 3 Along the radial direction of the second component 32, several anti-slip protrusions 5 are spaced apart; thereby increasing the friction between the user's hand and the pad when the user grips the second component 32 and the gripping part 22, so that the user can remove the pad.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
