Description

Technical Field

[0001] This utility model belongs to the field of packaging container technology, and specifically relates to a novel glass vacuum bottle. Background Technology

[0002] Existing glass vacuum flasks typically use plastic components to support the sealing ring. These plastic components pose a risk of plasticizer migration, which can contaminate the contents. Furthermore, the plastic components and the glass flask are manufactured separately, and subsequently integrating the plastic components into the glass flask presents assembly challenges, resulting in high assembly costs for glass vacuum flasks. Summary of the Invention

[0003] To avoid the above problems, this utility model designs a new type of glass vacuum bottle.

[0004] A novel glass vacuum bottle is provided, wherein a pump head is detachably connected to the opening of the glass bottle body. This pump head is existing technology. Pressing the pump head can spray the liquid in the glass bottle body out from the nozzle of the pump head. The specific structure of the pump head will not be described in detail here. The bottom of the glass bottle body has a through hole to communicate with the outside atmosphere. The inside of the glass bottle body is provided with an inner glass tube, and there is a sliding gap between the outer wall of the inner glass tube and the inner wall of the glass bottle body. The top of the concave glass tube is fitted with a sliding sealing sleeve. The side wall of the sliding sealing sleeve fits tightly against the inner wall of the glass bottle to achieve a vacuum seal. However, under atmospheric pressure, the sliding sealing sleeve can still slide along the inner wall of the glass bottle. Specifically: When the pump head is pressed, the contents of the glass bottle need to be pumped out. The external atmospheric pressure connected to the bottom through hole will push the sliding sealing sleeve and the inner glass tube inside the bottle to move upward, so as to transport the contents and finally spray them out from the nozzle of the pump head. During this process, the inner glass tube can support the relatively soft sliding sealing sleeve, maintaining a good sealing effect. Furthermore, since both the glass bottle body and the inner glass tube are integrally blown from high borosilicate glass using a hot-processing technique, the inner glass tube can be used as an internal component to support the unformed glass bottle body during blowing, reducing the difficulty of blowing the glass bottle body. This also makes it easier to directly embed the inner glass tube into the glass bottle body, avoiding subsequent assembly difficulties.

[0005] Preferably, the sliding sealing sleeve is made of silicone, which has good aging resistance and chemical stability, and is safe and environmentally friendly and will not contaminate the contents.

[0006] Preferably, the end of the inner glass tube near the sliding sealing sleeve is the sealing surface, and the sealing surface is in contact with the inner top surface of the sliding sealing sleeve. In this way, the external atmospheric pressure acts on the sealing surface of the inner glass tube to push the sliding sealing sleeve, avoiding direct pressure on the sliding sealing sleeve and causing it to deform.

[0007] Through the above technical solutions, this utility model has at least the following beneficial effects: The novel glass vacuum bottle described in this application has a significantly simplified structure and reduced manufacturing cost compared to traditional vacuum bottles. It uses an inner glass tube to replace traditional plastic parts, which is safe and environmentally friendly and will not contaminate the contents. The inner glass tube can support a softer sliding sealing sleeve, so that it can maintain a good sealing effect when sliding, effectively preventing leakage of contents and backflow of air, and ensuring the quality of the contents.

[0008] Furthermore, during the glass bottle blowing process, the inner glass tube can serve as an internal support structure, reducing the difficulty of forming the glass bottle. After forming, the inner glass tube is also directly located inside the glass bottle, avoiding subsequent assembly difficulties and resulting in lower assembly costs for the glass vacuum bottle.

[0011] In the description of this application, it should be understood that if terms such as "upper," "lower," "left," "right," "front," and "rear" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms describing positional relationships are for illustrative purposes only and should not be construed as limiting this patent. If terms such as "first" and "second" are used for descriptive purposes only, they should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of the stated features. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0012] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0013] refer to Figure 1 and Figure 2 A novel glass vacuum bottle is disclosed, wherein a pump head 2 is detachably connected to the opening of the glass bottle body 1. The pump head 2 is existing technology. Pressing the pump head 2 can spray the liquid inside the glass bottle body 1 out from the nozzle of the pump head 2. The specific structure of the pump head 2 will not be described in detail here. A through hole 101 is provided at the bottom of the glass bottle body 1 to communicate with the outside atmosphere. An inner glass tube 3 is provided inside the glass bottle body 1. There is a sliding gap between the outer wall of the inner glass tube 3 and the inner wall of the glass bottle body 1. The top end of the concave glass tube 3 is fitted with a sliding sealing sleeve 4. The side wall of the sliding sealing sleeve 4 fits tightly against the inner wall of the glass bottle body 1 to achieve the sealing effect of the vacuum bottle. Of course, under the action of atmospheric pressure difference, the sliding sealing sleeve 4 can still slide along the inner wall of the glass bottle body 1, specifically: When pump head 2 is pressed, and the contents of glass bottle 1 need to be pumped out, refer to... Figure 2 The external atmospheric pressure connected to the bottom through hole 101 will push the sliding sealing sleeve 4 and the inner glass tube 3 inside the bottle to move upward, so as to transport the contents and finally spray them out from the nozzle of the pump head 2. During this process, the inner glass tube 3 can support the relatively soft sliding sealing sleeve 4, so that it maintains a good sealing effect; and since both the glass bottle body 1 and the inner glass tube 3 are integrally blown from high borosilicate glass through a hot processing process, the inner glass tube 3 can be used as an inner component to support the unformed glass bottle body 1 during blowing, reducing the difficulty of blowing the glass bottle body 1. This also makes it easy to directly embed the inner glass tube 3 into the glass bottle body 1, avoiding subsequent assembly difficulties.

[0014] The sliding sealing sleeve 4 is made of silicone, which has good aging resistance and chemical stability, and is safe and environmentally friendly and will not contaminate the contents.

[0015] The end of the inner glass tube 3 near the sliding sealing sleeve 4 is the sealing surface 301. The sealing surface 301 is in contact with the inner top surface of the sliding sealing sleeve 4. In this way, the external atmospheric pressure acts on the sealing surface 301 of the inner glass tube 3 to push the sliding sealing sleeve 4, avoiding direct pressure on the sliding sealing sleeve 4 and causing it to deform, which would lead to a decrease in sealing performance.
