Description

Sealing device for anti-spring-plug container

Technical Field

The utility model belongs to the technical field of the container mouth encapsulation, concretely relates to shellproof stopper container sealing device.

Background

The container mouth packaging technology is an important research subject in the wine industry field. In the prior art, for example, white spirit is used, and plunger type sealing is widely used in the packaging technology of the mouth of a wine container. The plunger type sealing cover is characterized in that a cylindrical ceramic structure plug extends downwards from a cover to a mouth part, and a plastic or silica gel envelope is arranged at the contact part of the outside of the cylindrical structure plug and the mouth part, so that the plunger type sealing cover is used for sealing. The fatal weak points of plunger type closure sealing are: after the wine liquid is continuously evaporated in the bottle or the jar, the wine liquid can be condensed into liquid on the surface of the plastic or silica gel sleeve and then falls back into the container; the long-term circulation can cause the plasticizer or the rubber flavor to be brought into the wine body, thereby causing the wine body to be damaged and being not suitable for drinking again. In addition, the sealing structure only provided with a sealing cover or a sealing sleeve has the possibility of being re-packaged after the bottle is opened, and once the sealing structure is secondarily packaged, the sealing performance of the sealing structure is destroyed, so that the liquid in the bottle or the jar cannot be stored for a long time, and great trouble is brought to a user. Meanwhile, the plunger type sealing cover is matched with the jar opening or the jar opening in a way that the optical axis is in inserting connection with the hole shaft of the hole, when the sealing cover is plugged back to the jar opening or the jar opening again after secondary or repeated use, air enters the bottle or the jar, the air in the bottle or the jar resists the downward pressing action of the sealing cover, even the sealing cover is extruded from the jar opening or the jar opening due to air pressure in the subsequent storage process, and the phenomenon of spring plugging occurs, so that the plunger type sealing cover is required to be avoided to the greatest extent in the liquor industry, particularly in the liquor industry needing sealed preservation.

The beneficial effects of the utility model reside in that:

1) according to the above technical scheme, the utility model discloses rely on the sealed gum cover, realized the tight formula of expanding from the sealing function of fit clearance between closing cap and the container mouth to ensure the external leakproofness of wine liquid. In addition, sealed gum cover relies on forming between the cooperation arris of arc recess and container mouth department to cramp the screens cooperation to even when leading to the container to deposit certain air because of repeated opening and closing the closing cap, owing to constitute the tight structure of the formula of cramping of the bloated tight formula that forms between arc recess and cooperation arris, thereby can prevent effectively that the closing cap from receiving the phenomenon emergence that the change of container internal gas pressure leads to the closing cap to pop out. In addition, the sealing rubber sleeve is easy to assemble in the later period due to the elasticity and relative softness of the sealing rubber sleeve, and can conveniently press the extension section into the container opening in the manual axial direction and realize reliable positioning between the container opening and the sealing cover even if a matching edge exists, so that the sealing rubber sleeve is very convenient to use.

2) The appearance of the bottom end part of the extension section, extending out of the sealing rubber sleeve, is in a conical surface shape with the diameter gradually reduced vertically downwards, so that when the sealing cover is inserted into the container mouth, the extension section can be in a chamfer structure at the bottom edge of the extension section, the quick downward insertion operation of the sealing cover is more convenient, and the operation convenience is improved. Furthermore, the sealing rubber sleeve is actually thicker than the extension section, and therefore, the maximum diameter of the bottom end part of the sealing rubber sleeve is preferably larger than the maximum diameter of the bottom end part of the extension section, and at this time, the bottom end part of the conical surface of the extension section is positioned on the same conical surface with the outer chamfer of the bottom end part of the sealing rubber sleeve. Therefore, when the guiding action of the sealing cover relative to the container opening is executed, firstly, the conical surface structure at the bottom end part of the extension section is used for primarily correcting and guiding the downward inserting direction of the sealing cover in a rigid mode, then, the flexible outer chamfer angle at the bottom end part of the sealing rubber sleeve is used for secondarily correcting and carrying out protective guiding, at the moment, the force can be applied downwards, the sealing rubber sleeve is deformed and finally expands in the container opening, and the purpose of sealing the container opening is achieved.

3) On the basis of the structure, the tube cavity of the container opening is of a closing structure, namely the aperture of the top edge of the container opening is smaller than the tube diameter of the container opening and the top edge of the container opening is in smooth transition; therefore, when the sealing rubber sleeve matched with the contour of the container opening is clamped into the container opening, the closing structure of the container opening can naturally hoop the sealing rubber sleeve tightly, and the sealing rubber sleeve is always provided with downward axial pressure, so that the phenomenon that the sealing cover fixedly connected with the sealing rubber sleeve is axially upwards plugged is avoided. The top edge of the container mouth, i.e. the annular boundary line formed after the boundary between the wall of the lumen of the container mouth and the top end face of the container mouth, is described. In other words, the primary bulletproof plug structure is formed by the elastic concave-convex embedded matching of the sealing rubber sleeve and the container opening, and the secondary bulletproof plug structure is formed by the closing matching structure between the container opening and the sealing cover. Above-mentioned dual bullet proof plug system can further ensure the utility model discloses bullet proof plug reliability and stability.

4) As a further preferred aspect of the present invention, the closing structure of the container mouth can be subdivided into two different embodiments: firstly, the closing structure comprises a tube cavity of the whole container opening, namely the tube cavity of the container opening integrally presents a taper hole-shaped structure with small top aperture and large bottom aperture, and then the sealing rubber sleeve is arranged adaptively to be a matched frustum sleeve-shaped structure. At the moment, the tube cavity of the whole container opening and the sealing rubber sleeve have the function of preventing the bullet plug. Secondly, the closing structure is only positioned at a small area where the top edge of the container opening is positioned, and other positions of the tube cavities of other container openings are still normal straight hole tube cavities, so that the small area is really embedded and used for preventing the sealing cover from generating an axially upward spring plug action, and other matching parts do not have the spring plug prevention function. The above two embodiments can be selected as appropriate according to actual situations.

5) When containers such as wine bottles are opened, the sealing cover is often pulled out, but the sealing rubber sleeve is not easy to take out from the bottle mouth and even falls into the wine bottle, so that the phenomenon that the bottle is unplugged is called. As a further preferable scheme of the above scheme, when the positioning fit is formed between the sealing rubber sleeve and the container opening, the sealing rubber sleeve should also be simultaneously positioned and matched with the extending section of the sealing cover in a manner of matching the clamping groove and the protrusion, so as to realize the organic fit among the sealing cover, the sealing rubber sleeve and the container opening, and effectively avoid the above-mentioned plug-off phenomenon.

6) For the sealing rubber sleeve, firstly, the sealing requirement of the extension section relative to the container opening is met, and secondly, the flanging is arranged at the top end face of the sealing rubber sleeve, so that the mutual sealing effect between the shaft shoulder of the sealing cover and the top end face of the container opening is realized by the flanging structure, and the sealing performance between the sealing cover and the container opening is improved by expanding the sealing area between the sealing cover and the container opening. In addition, when the sealing cover is inserted downwards relative to the container opening, the shaft shoulder of the sealing cover easily directly impacts the top end surface of the container opening, so that the sealing cover or the container opening is easily scratched or even cracked, and the outward flanging of the sealing rubber sleeve can play a certain buffering role so as to ensure the actual service life of the sealing cover and the container opening by utilizing the flexibility of the outward flanging per se, thereby achieving multiple purposes.

Detailed Description

For the sake of understanding, the structure and the working flow of the present invention are further described herein with reference to fig. 1 to 3:

the wine bottle mouth seal shown in fig. 1-3 is taken as an example, that is, the mouth at this time is the container mouth a. Of course, in actual use, the radiation can be radiated into the packaging structure of other similar containers such as wine jars and the like so as to achieve the purpose of preventing the bullet plug. For ease of viewing, hatching of the closure 10 and container finish a in fig. 1-3 is removed without affecting the understanding of the graphics.

The structure of the utility model after the concrete implementation and installation is shown in figures 1-3: the lowest part is a container opening a of the wine bottle, and the top end surface of the container opening a is covered with a sealing cover 10 made of ceramics or similar materials. The sealing cover 10 and the container mouth a or the sealing rubber sleeve 20 can be used for sealing, and a mode of additionally matching a sealing ring and adopting a smooth inclined surface or even a frosted surface to form two sealing can be considered to prevent the volatilization of liquid such as wine and the like.

Specifically, as shown in fig. 1-3, when the present invention is used as a bottle closure for a wine bottle, the shape of the bottle closure, and thus the closure cap 10, can be varied artistically as appropriate depending on the existing structure. Regardless of how the shape of the bottle mouth and thus the closure 10 is changed, the mating configuration of the bottle mouth and the closure 10 must be sealed with a sealing rubber 20. In operation, the bottom end of the closure 10 extends downwardly to form an extension 11 that extends into the bottle mouth and cavity. Because the extension section 11 is shaped like a straight round rod, a two-section stepped shaft structure is formed between the extension section and the upper part of the sealing cover 10. When in use, the sealing cap 10 is inserted into the bottle mouth from top to bottom, and the extension section 11 is guided to extend into the bottle mouth and the bottle cavity by the conical surface structure at the bottom end. The extending section 11 is provided with a positioning protrusion and a ring-shaped clamping groove 11a or a positioning groove and a ring-shaped protrusion 11b, so that the sealing rubber sleeve 20 can be effectively prevented from generating axial motion along the extending section 11.

On the basis of the structure, as shown in fig. 2-3, the utility model discloses the binding off structure that sets up in container mouth a lumen department. The closing structure or the tube cavity covering the whole container opening a as shown in fig. 2, that is, the tube cavity of the container opening a is integrally in a taper hole-shaped structure with a small top aperture and a large bottom aperture, and at this time, the sealing rubber sleeve 20 is adaptively arranged to be in a matched frustum sleeve-shaped structure. At this time, the anti-plug function is provided between the lumen of the container opening a and the sealing rubber sleeve 20. Or as shown in fig. 3, the closing structure is only located in a small area where the top edge of the container opening a is located, so that the top edge of the container opening a forms a cornice b, and the other positions of the tube cavities of the other container openings a are still normal straight-hole tube cavities. Thus, the actual engagement and prevention of the axially upward movement of the closure 10 is a small area of the cornice b as shown in fig. 3, and the other engagement portions do not have the anti-jamming function. The above two embodiments can be selected as appropriate according to actual situations.

In fact, whether the closing structure encloses the whole lumen of the container mouth a or only forms a small closing at the top edge of the container mouth a, an arc-shaped groove 21 is coaxially recessed at the outer wall of the sealing rubber sleeve 20 as shown in fig. 1-3, and a matching edge matched with the arc-shaped groove 21 is correspondingly arranged at the lumen of the container mouth a. Through the cooperation of arc recess 21 and cooperation arris, can realize closing cap 10 relative to the secondary structure of bullet stopper of preventing of container mouth a. In other words, on the basis that the primary anti-spring-stopper structure is formed by the closing structure at the tube cavity of the container opening a, the secondary anti-spring-stopper structure of the sealing cover 10 relative to the container opening a can be realized by the elastic snap-fit matching of the arc-shaped groove 21 and the matching edge. Above-mentioned dual bullet proof plug system can further ensure the utility model discloses bullet proof plug reliability and stability.
