Description

Technical Field

[0001] This utility model relates to the field of sealing film technology, and specifically to a sealing structure for condiment bottles. Background Technology

[0002] Existing condiment bottles all have caps with several small holes for dispensing, and the bottle opening is heat-sealed with a sealing film. The bottle contains condiments. To use them, first unscrew the cap, tear off the sealing film, and then screw the cap back onto the bottle opening. The condiments can then be poured out from the dispensing port. However, because the existing caps have poor sealing performance, the condiments are prone to moisture absorption and need to be improved. Utility Model Content

[0003] To address the above problems, this utility model provides a sealing structure for a condiment bottle, thereby solving one or more technical problems existing in the prior art, and at least providing a beneficial option or creating conditions.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A sealing structure for a condiment bottle includes a bottle body, a sealing film, and a bottle cap. The sealing film is fixed to the bottle opening of the bottle body, and the bottle cap is tightly fitted to the bottle opening. The sealing film includes a bottom layer and a top layer. The bottom layer is fixedly connected to the bottle opening and also has several discharge holes through it, forming a discharge area. The top layer is pasted on top of the bottom layer. The connection strength between the top layer and the discharge area is weaker than the connection strength between the top layer and areas outside the discharge area. The top layer has a tear line at the edge corresponding to the discharge area. A gasket adapted to the sealing film is provided inside the bottle cap.

[0006] Preferably, the discharge zone is located at the center of the bottle opening.

[0007] Preferably, the surface layer has a handle extending from the edge of the corresponding discharge area.

[0008] Preferably, the bottom layer is composed of two or more layers of composite materials.

[0009] Preferably, the surface layer is composed of three or more layers of materials.

[0010] Preferably, the liner is foamed PE, foamed PS, foamed EVA or foamed PP.

[0011] The beneficial effects of this utility model are:

[0012] This invention features a discharge area and discharge hole at the bottom of the sealing film, with the top layer adhered to the bottom layer. This design facilitates moisture prevention during seasoning storage. To use, simply unscrew the cap and peel off the top layer to pour the seasoning out of the discharge hole. After use, tighten the cap, and the gasket will seal the discharge hole to prevent the seasoning from getting damp.

[0013] The surface layer has tear lines at the edge of the corresponding discharge area, which makes it easy to tear the surface layer of the corresponding discharge area to expose the discharge hole.

[0014] A handle is provided on the edge of the corresponding discharge area through the surface layer, making it easy to quickly tear open the surface layer above the discharge area when using it.

[0015] The gasket inside the bottle cap acts as a buffer and sealant. When the cap is tightened, the gasket seals the bottle opening, minimizing the entry of external moisture into the bottle and extending the product's lifespan after opening. Attached Figure Description

[0019] Explanation of the labels in the attached diagram: 1. Bottle body; 2. Sealing film; 3. Bottle cap; 4. Bottom layer; 5. Top layer; 6. Discharge hole; 7. Discharge area. Detailed Implementation

[0020] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0021] Example: Refer to Figures 1 to 2 The present invention discloses a sealing structure for a condiment bottle, comprising a bottle body 1, a sealing film 2, and a bottle cap 3. The sealing film 2 is fixed at the bottle mouth of the bottle body 1, and the bottle cap 3 is tightly fitted to the bottle mouth. The sealing film 2 includes a bottom layer 4 and a top layer 5. The bottom layer 4 is fixedly connected to the bottle mouth and also has several discharge holes 6 extending through it, forming a discharge area 7. The top layer 5 is pasted on top of the bottom layer 4. The connection strength between the top layer 5 and the discharge area 7 is weaker than the connection strength between the top layer 5 and areas other than the discharge area 7. The top layer 5 has a tear line corresponding to the edge of the discharge area 7. The tear line is formed by cutting the top layer 5 in half. When the top layer 5 is torn, the tear line is torn first, and the discharge area 7 can be completely exposed, allowing the condiment to be poured out from the discharge holes 6. The bottle cap 3 has a liner adapted to the sealing film 2. The liner is composed of plastic foam and PET composite from bottom to top. When the bottle cap 3 is screwed back, the liner seals the discharge holes 6 to prevent the condiment from getting damp.

[0022] Specifically, the discharge area 7 is located in the center of the bottle mouth. When the bottle mouth is sealed by induction, the aluminum foil at the edge of the bottle mouth generates more heat than that at the center of the bottle mouth. Since the discharge area is located in the center, the surface layer 5 will not stick too tightly to the bottom layer 4, making it easier to peel off the bottom layer 5 during use.

[0023] Specifically, the surface layer 5 has a handle extending from the edge of the corresponding discharge area 7, making it easy to tear off the corresponding surface layer 5 on the discharge area 7.

[0024] Specifically, the bottom layer 4 is composed of two or more layers of materials. When the bottle body 1 is made of PE, the bottom layer 4 is composed of PET, aluminum and PE layers from bottom to top. The aluminum layer facilitates electromagnetic induction heating, which allows the materials on both sides to quickly adhere to the aluminum layer. When the bottle body 1 is made of PET, the bottom layer 4 is composed of PET, PE and PET from bottom to top. The multi-layer material composite can improve the strength and sealing performance of the bottom layer 4.

[0025] Specifically, the surface layer 5 is composed of three or more layers of materials. It can be composed of PET, paper, and PET from bottom to top, or it can be composed of PET, aluminum, and PET. The aluminum layer facilitates electromagnetic induction heating, allowing the materials on both sides to be quickly bonded to the aluminum layer. The three-layer configuration improves the strength of the surface layer 5.

[0026] Specifically, the gasket is made of foamed PE, foamed PS, foamed EVA or foamed PP. When the top layer 5 is peeled off, the gasket inside the bottle cap can act as a buffer sealing gasket. When the bottle cap is tightened, the gasket inside will seal the bottle opening, minimizing the entry of moisture from outside the bottle into the bottle and extending the product's service life after opening.
