Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of containers, in particular to a barrier container with high barrier performance. Background Art
[0002] Containers are often used to store and preserve various products. In many products sold, the container not only plays the role of storing and packaging products, but also needs to prevent external oxygen and water vapor from contacting the products inside the container, prevent product deterioration, and increase the shelf life of the products.
[0003] Plastic materials and metal materials are common materials used to make containers.
[0004] Plastic has strong plasticity and can be easily made into various shapes through molds, which not only meets the storage function of products but also meets the operational convenience of using the container. However, for some products with high barrier requirements, the barrier property of plastic is difficult to meet the long-term storage requirements of the products, and the shelf life of products using plastic materials as containers for such products will be relatively short. At this time, containers made of metal materials are needed to extend the shelf life of the products. However, it is difficult to form metal materials, and they are only suitable for making some simple shapes. If made into more complex shapes, machining methods need to be adopted, with many processes and very high processing costs. Therefore, it is very difficult to process metal containers into complex shapes that are beneficial to operation and use (such as positioning and fixing). Summary of the Utility Model
[0005] The technical problem to be solved by the utility model is to provide a high-plasticity barrier container with high barrier performance and favorable for processing.
[0006] The technical solution adopted to solve the above technical problem: A barrier container includes a bottle body and a bottle cap. The bottle body is composed of an outer shell and an inner liner, and the bottle cap seals the bottle mouth of the bottle body. Its characteristics are that the bottom of the bottle body is open, and a sealing bottom plug is blocked in the open part.
[0007] On the above basis, the bottle mouth is set as an inner-liner bottle mouth and an outer-shell bottle mouth separated from each other inside and outside. Correspondingly, the bottle cap has an inner cap and an outer cap separated from each other inside and outside. The outer cap covers the outer-shell bottle mouth, and the inner cap seals and covers the inner-liner bottle mouth and is threadedly connected to the outer-shell bottle mouth.
[0008] On the above basis, the outer shell is a plastic outer shell, and the inner liner is a metal inner liner.
[0009] Advantages brought by the present utility model: Since the bottom of the bottle body of the barrier container of the present utility model is designed with an open mouth, the inner container can be processed from a metal barrier material by a simple tubular forming process, with simple process and low cost. Its outer shell is processed by a traditional simple injection molding process, which is also simple in process and low in cost, and can also be processed into various shapes beneficial to operation and use. Brief Description of the Drawings
[0010] Figure 1 It is a schematic cross-sectional structure view of the barrier container of the present utility model. Detailed Description of the Preferred Embodiment
[0011] As Figure 1 shown, a barrier container includes a bottle body 1 and a bottle cap 2, and the bottle body 1 is composed of a composite of an outer shell 11 and an inner container 12. The bottle cap 2 covers the bottle mouth of the bottle body 1. Among them, the inner container 12 is the barrier layer of the barrier container, and the outer shell 11 is an operation outer shell that forms a shape beneficial to operation in some application scenarios. In the present utility model, the bottom of the bottle body 1 is open, and a sealingly matched bottom plug 3 is blocked in the open mouth. For the bottle body 1 with an open bottom, the overall structure of the inner container 12 is a tubular structure with both ends open, and a metal barrier material can be processed into the inner container 12 by a simple tubular forming process. The outer shell 11 is also processed into various shapes beneficial to operation and use by a traditional simple injection molding process. Therefore, the barrier container of the present utility model has the characteristics of being easy to process and low processing cost. In this embodiment, the sealing cooperation between the bottom plug 3 and the open bottom of the bottle body 1 adopts a conventional sealing ring 4 for sealing.
[0012] Generally, the connection between the bottle cap 2 and the bottle mouth of the bottle body 1 all adopts a threaded connection. Inevitably, there will be a problem of slipping teeth caused by the deformation of the material itself in this connection method, resulting in poor sealing. To enhance the threaded sealing performance of the bottle cap of the barrier container, the bottle mouth can be set as an inner container bottle mouth 12.1 and an outer shell bottle mouth 11.1 that are separated inside and outside. Correspondingly, the bottle cap 2 has an inner cover 2.1 and an outer cover 2.2 that are separated inside and outside. Among them, the outer cover 2.2 covers the outer shell bottle mouth 11.1, and the inner cover 2.1 sealingly covers the inner container bottle mouth 12.1 and is threadedly connected to the outer shell bottle mouth 11.1. Since the threadedly connected inner cover 2.1 and the outer shell bottle mouth 11.1 are clamped between the outer cover 2.2 and the inner container bottle mouth 12.1, the deformation of the inner cover 2.1 and the outer shell bottle mouth 11.1 is restricted, effectively solving the problem of slipping teeth of the bottle cap and improving the sealing performance of the barrier container.
