Description

Technical Field

[0001] The utility model relates to the technical field of containers, in particular to a paste bottle. Background Art

[0002] In modern life, people use containers for pastes, such as perfume bottles. Existing perfume bottles are basically disposable, and the bottles are discarded after the paste is used up. This not only causes waste of materials, but also causes environmental pollution because plastic waste is not easy to degrade, and causes ecological disasters because the small plastic parts are easily swallowed by animals.

[0003] On the other hand, existing containers for pastes, such as perfume bottles, have poor sealing performance, and volatile substances in the product can easily escape from the joints of the bottle to the outside. For products containing volatile materials, containers with poor sealing performance will cause the active ingredients of the product to volatilize before use, reducing the performance and use effect of the product, and also polluting the product transportation and storage space.

[0004] Existing paste bottles have a replaceable inner bottle structure, but due to sealing reasons, usually only solid pastes can be used, which cannot meet the requirements of soft gel products. Utility Model Content

[0026] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Further, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-on, one-piece fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.
