Description

Technical Field

[0001] The utility model relates to the technical field of lead-free glass sealing, in particular to a lead-free glass sealing component of a vacuum container. Background Art

[0002] Currently, the main method of keeping food fresh at home is to use a home refrigerator, but this is limited when traveling, and food in the freezer must be thawed before cooking. Conventional bottled foods are not vacuum-packed, so their shelf life is short. While canned foods can be vacuum-packed for a longer period of time, once opened, the can cannot be reused, so a sealing lid is required.

[0003] Application number CN201120018855.9 discloses a hygienic, safe, and durable silicone glass lid. The glass lid comprises a glass lid body and a lid handle. The glass lid body is provided with a silicone vent, each with an opening. The opening is preferably cross-shaped. The edges of the glass lid are sealed with a silicone edge guard. Specifically, this application is used to prevent the glass lid from shifting, which could lead to a failure to seal a vacuum container. Utility Model Content

The sealing mechanism includes a glass cover, a protrusion connected to the top of the glass cover, a sealing sleeve sleeved on the outside of the glass cover, and a binding mechanism. The binding mechanism includes a metal ring movably connected to the glass cover, a tightening belt connected to the metal ring, and multiple circular openings opened on the tightening belt.

[0007] By adopting the above technical solution, the glass cover is covered on the port of the vacuum container, and then the sealing sleeve is used to make the glass cover and the port of the vacuum container fit in an interference fit. Then, the tightening belt is stretched so that the tightening belt is covered on the bottom end of the vacuum container, and then the tightening belt is stretched upward so that the round end of the tightening belt is covered on the protrusion, thereby tightening the tightening belt and improving the connection strength between the glass cover and the vacuum container.

[0008] In a preferred example, the present invention can be further configured as follows: the glass cover is set in a "⊥" shape and is made of lead-free glass.

[0009] In a preferred example, the present invention can be further configured as follows: the protrusion is composed of a short rod and a ball head, the ball head is fixed to the top of the short rod, the diameter of the ball head is larger than the diameter of the short rod, and the short rod is vertically coaxial with the glass cover.

[0010] In a preferred example, the present invention can be further configured as follows: the tightening band is movably sleeved on the bottom of the glass cover, and the tightening band is made of elastic material.

[0011] In a preferred example, the present invention can be further configured as follows: a plurality of circular openings are respectively located on both sides of the metal ring, and the diameter of the circular openings is equal to the diameter of the short rod.

[0012] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0013] In the utility model, the glass cover is covered on the port of the vacuum container, and then the sealing sleeve is used to make the glass cover and the port of the vacuum container fit in an interference fit. Then, the tightening belt is stretched so that the tightening belt is sleeved on the bottom end of the vacuum container, and then the tightening belt is stretched upward so that the round end of the tightening belt is sleeved on the protrusion, thereby tightening the tightening belt and improving the firmness of the connection between the glass cover and the vacuum container.

[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0022] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0023] A lead-free glass sealing assembly for a vacuum container provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0024] Example 1:

[0025] Combine Figure 1-4 As shown, the present invention provides a lead-free glass sealing assembly for a vacuum container, comprising a sealing mechanism 100 and a binding mechanism 200. The sealing mechanism 100 comprises a glass cover 110, a protrusion 120 connected to the top of the glass cover 110, and a sealing sleeve 130 sleeved on the outside of the glass cover 110.

[0026] The tightening mechanism 200 includes a metal ring 210 movably connected to the glass cover 110 , a tightening belt 220 connected to the metal ring 210 , and a plurality of circular openings 230 opened on the tightening belt 220 .

[0027] Furthermore, the glass cover 110 is configured to be in a “⊥” shape and is made of lead-free glass. Lead-free glass does not contain toxic heavy metal lead, and is therefore safer to use and poses no threat to human health.

[0028] Furthermore, the protrusion 120 is composed of a short rod 121 and a ball head 122. The ball head 122 is fixed to the top of the short rod 121. The diameter of the ball head 122 is larger than the diameter of the short rod 121. The short rod 121 is vertically coaxial with the glass cover 110. The structural design of the protrusion 120 ensures that the protrusion 120 can limit the tightening belt 220 so that the tightening belt 220 can be tightened.

[0029] Example 2:

[0030] Combine Figure 1 and Figure 3 As shown, based on the first embodiment, the tightening belt 220 is movably sleeved on the bottom of the glass cover 110. The tightening belt 220 is made of elastic material. By using elastic material to make the tightening belt 220, the tightening belt 220 can be stretched as much as possible, thereby indirectly improving the firmness of the connection between the glass cover 110 and the vacuum container.

[0031] Example 3:

[0032] Combine Figure 1 and Figure 3 As shown, in the above embodiment, multiple circular openings 230 are respectively located on both sides of the metal ring 210 , and the diameter of the circular opening 230 is equal to the diameter of the short rod 121 . The size design of the circular opening 230 enables the protrusion 120 to limit the tightening belt 220 .

[0033] The working principle and usage process of the present invention are as follows: When the device is put into actual use, the glass cover 110 is covered on the port of the vacuum container, and then the sealing sleeve 130 is used to make the glass cover 110 and the port of the vacuum container fit in an interference fit. Then, the tightening belt 220 is stretched so that the tightening belt 220 is sleeved on the bottom end of the vacuum container, and then the tightening belt 220 is stretched upward so that the round mouth 230 on the tightening belt 220 is sleeved on the protrusion 120, thereby tightening the tightening belt 220 to improve the connection firmness between the glass cover 110 and the vacuum container.

[0034] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
