technical field

The invention relates to a sealed container, in particular to cups, bottles, jars and other containers that need to be sealed.

Background technique

The existing sealed containers in the market, such as cups, bottles, jars, etc., are generally sealed with lids, and the inside of the lids are equipped with sealing rings or gaskets made of silica gel or other plastic materials. When the top part is docked with the cover, the opening end of the container just corresponds to the position of the sealing ring, and the sealing can be realized due to the deformation of the sealing ring when the cover is pressed. However, in this sealing method, the materials in the container will directly contact the container lid and the sealing ring. Since the container lid itself is made of various materials, silicone or other plastic materials are easy to age after long-term use, and the metal substrate is easy to corrode or contain heavy metals. , and the use of higher-level or specification materials to make containers faces high costs. In this way, when the material in the container must require a higher degree of cleanliness or higher pollution-free requirements or the material has a corrosive effect, the sealing method of the prior art cannot be well applied here.

The content of the present invention will be further described below in conjunction with the accompanying drawings, but the description is not a simple limitation on the protection scope of the invention.

Example 1

As shown in Figure 1, the sealed container of the present invention is a glass container such as a glass or a glass bottle or a glass jar, which includes a container body 9 provided with a container opening 10 and a container cover located at the container opening 10, The container cover comprises a planar structure part 2 and a ring structure part 1, and the lower surface of the planar structure part 2 is provided with a plane sealing plate 6, which is a glass plate with a flat lower surface, which can cover the lower surface of the planar structure part , a gasket 31 is arranged between the lower surface of the plane structure part 2 and the plane sealing plate 6, and the gasket is arranged along the peripheral edge portion of the plane sealing plate 6; The lower surface is also flat, and the flatness of the opening end face is consistent with that of the lower surface of the sealing plate. In this way, when the opening end face of the container opening 10 is docked with the plane sealing plate, there is a basis for sealing, and tight seam fit and sealing performance can be ensured. In this sealed container, a step 4 for clipping the flat sealing plate 6 is also provided on the inner surface top of the ring structure part 1, so that the flat sealing plate 6 can be preferably arranged on the lid; The thread design of the part, the inner surface of the ring structure part 2 is also provided with thread 5, that is, the container cover is designed as a screw gland, of course, the connection method between the container cover and the container opening can also be other connection methods such as threaded connection. Clamping, etc., as long as it can realize the fixation after the sealing plate and the opening end surface of the container are flattened. If the container needs to be sealed, the container cap is spun, and the flat sealing plate 6 is completely flat, but due to the height of the thread, the opening end face of the container opening 10 will first contact the flat sealing plate 6 in one direction, and continue spinning, because the gasket above The deformation effect makes the opening end surface of the container opening 10 contact with the flat sealing plate 6 successively in other directions until the opening end surface of the container opening 10 is in close contact with the flat sealing plate 6 in all directions to realize sealing.

Example 2

As shown in Figure 2, it is another container cover structure of a sealed container of the present invention, the container body 9, the container cover and other structures are the same as in Embodiment 1, except that between the lower surface of the planar structure part 2 and the planar sealing plate 6 Spacer 32 is arranged between, and this spacer is arranged symmetrically with the central axis of container cover, and the size of this spacer can be covered with the upper surface of whole plane sealing plate 6, also can only spread a part as shown in Figure 2. The sealing principle of the sealed container structure of this example is the same as that of Embodiment 1.

Example 3

As shown in Figure 3, it is the container cover structure of the third kind of airtight container of the present invention, container body 9, container cover and other structures are identical with embodiment 1, just between the lower surface of planar structure part 2 and planar sealing plate 6 Spacer 33 is arranged between, and this spacer is spherical shape, and it is better that this spacer is arranged symmetrically with the central axis of container lid, and it is fixed on the lower surface of plane structure part 1, and when container needs to be sealed, spinning For the container cover, the flat sealing plate 6 is completely flat, but due to the thread height process, the opening end face of the container opening 10 will first contact the flat sealing plate 6 in one direction, and continue spinning, because the block 33 above is blocked, and the block 33 is formed. When the fulcrum is reached, the plane sealing plate 6 will form a seesaw shape, and if the spinning is continued, the other directions of the opening end surface of the container opening 10 will also contact the plane sealing plate 6 one after another until all directions of the opening end surface of the container opening 10 are sealed with the plane. The plates 6 are in close contact to achieve sealing. In this structure, the pad 33 is spherical, and the hard material can be hard plastic PP, PC, PPSU, PES, etc., so that the flat sealing plate 6 can swing universally on the spherical surface with the pad 33 as the fulcrum. ; and when the material of the spacer is the same as that of the base body of the container cover, the spacer forms an integral body with the container cover or becomes a part of the container cover, which obviously will be more conducive to the making of the structure. Since the spacer 33 is spherical, when the flat sealing plate contacts the spacer, the flat sealing plate 6 can swing universally on the spherical surface with the spacer 33 as a fulcrum, so that the opening end surface of the container opening 10 is in contact with the flat sealing plate. 6 Finally, close contact is achieved to achieve a seal. Of course, the pad 33 can also be fixed on the upper surface of the plane sealing plate 6 to achieve the same sealing.

Example 4

As shown in Figure 4-5, be the container cover structure of the 4th kind of airtight container of the present invention, container body 9, container cover and other structures are identical with embodiment 1, but the sealing plate that adopts is type sealing plate 7, and the container cover is provided with a decompression valve 16 and a decompression button 17, the opening end face of the container opening 10 is flat, and the The contact surface of the type sealing plate is flat, and the flatness of the opening end face is the same as The flatness of the contact surface of the type sealing plate is consistent. This structural design, The space between the type sealing plate 7 and the planar structure part 2 is relatively large, so that the pressure relief valve 16 can be set, and the design of the pressure relief valve 16 can make the airtight container of the present invention hold superheated or supercooled materials when it is opened. , to deflate or intake air to balance the air pressure inside and outside the container, so that it is easier to open the container cover. The sealing principle of the sealed container structure of this example is similar to that of Example 1. The invention omits various (silicon) rubber pad materials used in traditional sealing methods, removes plastic odor, reduces secondary pollution, is acid and alkali resistant, and durable.

For the container structure of embodiment 4, a typical one is a thermal insulation glass. In this structure, a stainless steel outer layer 11 can also be set on the outer peripheral cylindrical surface of the container cover (bowl cover); Groove, the groove divides the outer peripheral edge portion of the upper surface of the container cover into a first raised portion 12 and a second raised portion 13, and the upper end of the stainless steel outer layer 11 wraps the first raised portion 12 and bends it on the in the groove. The groove can be used as a flanging space for the peripheral edge when the stainless steel outer layer covers the outer surface of the container cover. At the same time, the setting of the groove makes the outer peripheral edge of the upper surface of the container cover divided into two protrusions, wherein. The first raised portion 12 is covered by the stainless steel outer layer, and the second raised portion 13 is not covered by the stainless steel outer layer, that is, the upper end of the stainless steel outer layer 11 is just right after the first raised portion 12 is covered. Bending in the groove (because the groove space is occupied by the upper end of the stainless steel outer layer 11 in the figure, so it is not marked), this design makes the stainless steel end not exposed on the one hand, which is safe, and on the other hand, due to The thickness of the stainless steel outer layer makes the horizontal edge of the overall outer surface of the container cover have a certain protrusion, thereby avoiding the problem that the cup cover is not easy to take when it is inverted on a smooth surface such as a glass table, especially when there is water on the clean table; at the same time The lower end of the container cover ring structure part is provided with a gap, and the lower end of the stainless steel outer layer 11 is just bent at the gap (the gap space is occupied by the lower end of the stainless steel outer layer 11 in the figure, so it is not shown). The upper and lower ends of the stainless steel outer layer 11 all adopt the above-mentioned bending design. On the one hand, the ends of the stainless steel outer layer are just not exposed and protruding, which is safe; on the other hand, the upper and lower ends of the stainless steel outer layer are respectively After being bent in the groove and notch, the outer layer of stainless steel and the container cover will also form a tight fit structure, and the outer layer of stainless steel will not be separated during spinning, and if the upper and lower ends of the outer layer of stainless steel are not folded When the spinning pressure is too large or the spinning pressure is too large, it is easy to cause the outer layer of stainless steel to separate from the container cover, especially when storing supercooled or overheated materials, due to the difference between the thermal expansion and contraction deformation rate of the stainless steel outer layer material and the container cover material Different, it is easier to cause the separation of the stainless steel outer layer and the container cover. Therefore, the bending design of the end of the stainless steel outer layer ensures the overall practicability and neat appearance of the lid structure; in addition, the rounded corners of the stainless steel outer layer 11 also effectively ensure the safety and the integrity of the container lid structure. Functionality meets beauty. In addition, the upper surface of the container cover can also be provided with a printed layer 14, and a transparent material layer 15 is provided on the upper surface of the printed layer.
