Description

Technical Field

[0001] This utility model relates to the field of plastic container technology, specifically to a plastic container with a double-layer sealing structure. Background Technology

[0002] Plastic containers, also known as hollow blow-molded containers, are manufactured using a hollow molding method. They include open-top and closed-top plastic buckets and cans. Open-top plastic buckets and cans are mainly used for storing solid chemicals, food, and pharmaceuticals; closed-top plastic buckets and cans are mainly used for storing liquids. They are lightweight, not easily broken, corrosion-resistant, and recyclable. However, existing plastic containers often have poor sealing properties and are not very efficient at storing contents. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the prior art by providing a plastic container with a double-layer sealing structure, so as to solve the problems mentioned in the background art, which are that the existing plastic containers have poor sealing effect and poor storage effect during installation and use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a plastic container with a double-layer sealing structure, including a bottle body structure, and a bottle cap structure is provided on the top of the bottle body structure;

[0005] The bottle structure includes a bottle bottom with a connecting seat, and an adsorption block is embedded and fixedly installed above the connecting seat. At the same time, a flexible silicone body is embedded and fixedly installed at one end above the connecting seat.

[0006] The other end of the flexible silicone body is installed and connected to the bottom of the bottle neck with a threaded opening.

[0007] By adopting the above technical solution, the flexible silicone body can be used to achieve folding and storage under pressure.

[0008] Preferably, a recessed platform is fixedly installed below the bottleneck, and a magnet is embedded and fixedly installed below the recessed platform, while a hanging hook is fixedly installed on one side of the recessed platform.

[0009] By adopting the above technical solution, the suspension hooks are installed to achieve the function of suspension and carrying.

[0010] Preferably, the bottle cap structure includes a bottle cap body with connecting threads, and a rubber pad is fixedly installed at the bottom of the bottle cap body. At the same time, a plastic bearing seat is fixedly installed inside the rubber pad, and a silicone rod is installed at the bottom of the plastic bearing seat.

[0011] By adopting the above technical solution, the plastic bearing housing is used to fix and install the bearings.

[0012] Preferably, the adsorption blocks are arranged in a ring array.

[0013] By adopting the above technical solution, the adsorption block is set to achieve adsorption limitation.

[0014] Preferably, the silicone rod is T-shaped.

[0015] By adopting the above technical solution, the silicone rod is used to achieve a blocking and sealing effect.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the plastic container with a double-layer sealing structure,

[0017] (1) This case solves the problem of poor sealing effect and poor storage effect of existing plastic containers during installation and use by setting the bottle cap structure. When the threaded bottle mouth needs to be sealed, the silicone rod and rubber gasket block and seal the inside of the threaded bottle mouth and the edge of the bottle mouth. After the inside and edge of the bottle mouth are blocked and sealed, the bottle cap body wraps and seals the entire threaded bottle mouth through the threaded connection. The three-layer seal is used to avoid the problem of poor sealing.

[0018] (2) By setting the bottle structure, the above problems are solved. When the plastic container needs to be stored, when the operator squeezes the bottom and neck of the bottle, the flexible silicone body is squeezed and stored inside the concave platform, thereby shortening the overall length of the plastic container and making it convenient to store and carry the overall plastic container.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-7 This utility model provides a technical solution: a plastic container with a double-layer sealing structure, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the device includes a bottle structure 1, which includes a bottle bottom 101 with a connecting seat 102. An adsorption block 103 is embedded and fixedly installed above the connecting seat 102. The adsorption blocks 103 are arranged in a ring array. When the components are arranged in a ring array, it not only reflects the equidistant distribution of the components, but also the practicality of the installation and the contact adsorption limiting function of the components. Furthermore, when the components are arranged in a ring array, it reflects the axial and longitudinal axial symmetry of the components, as well as the aesthetic appeal of the equidistant distribution of the components. At the same time, a flexible silicone body 104 is embedded and fixedly installed at one end above the connecting seat 102.

[0029] Furthermore, a recessed platform 107 is fixedly installed below the bottleneck 105, and a magnet 108 is embedded and fixedly installed below the recessed platform 107. At the same time, a hanging hook 109 is fixedly installed on one side of the recessed platform 107. The magnets 108 are arranged in the same number, and the use of the above-mentioned components in the same number can effectively achieve the same number of adsorption and limiting.

[0030] like Figure 6 and Figure 7As shown, a bottle cap structure 2 is provided above the bottle body structure 1. The bottle cap structure 2 includes a bottle cap body 201 with connecting threads, and a rubber gasket 202 is fixedly installed at the bottom of the bottle cap body 201. At the same time, a plastic bearing seat 203 is fixedly installed inside the rubber gasket 202. A silicone rod 204 is installed at the bottom of the plastic bearing seat 203. The silicone rod 204 is T-shaped. The T-shaped shape of the above components not only reflects the matching installation of one end of the components, but also reflects the sealing performance of the other end of the components. Furthermore, the T-shaped shape of the above components reflects the quick insertion and sealing performance and multi-layer sealing performance of the installation. At the same time, the T-shaped shape of the above components reflects the practicality of the installation.

[0031] In the above scheme, when the threaded bottle neck 106 needs to be sealed, the silicone rod 204 and the rubber pad 202 block and seal the inside and edge of the threaded bottle neck 106. After the inside and edge of the bottle neck are blocked and sealed, the bottle cap body 201 can wrap and seal the entire threaded bottle neck 106 through the threaded connection.
