Description

Technical Field

[0001] The utility model relates to the field of bottle stoppers, in particular to a stopper cover and a bottle stopper using the stopper cover. Background Art

[0002] Bottle stoppers are a type of tool used to prevent the contents of various volumetric flasks from spilling or dispersing. Bottle stoppers can be classified by material into: wooden stoppers, glass stoppers, plastic stoppers, and more.

[0003] Existing composite bottle stoppers have caps typically made of a rigid material and head-stoppers made of an elastic plastic material. Patent publication number CN202642356U discloses a bottle stopper. After the stopper and cap are fabricated, they are bonded together using an adhesive. The stopper and cap are axially positioned using a mortise and tenon joint.

[0004] Although the structure of the above-mentioned plug relies on the expansion resistance of the material to enable the plug cover and the plug to be circumferentially linked, during the long-term use of the plug, when the cover is rotated circumferentially, the plug head and the plug cover may slip against each other, affecting the normal use of the plug. Utility Model Content

[0005] In view of this, the first object of the present invention is to provide a plug cover that can prevent the plug cover and the plug head from slipping.

[0006] In order to solve the above technical problems, the technical solution of the present invention is: a plug cover, including a plug cover body, the plug cover body is provided with a mounting hole for mounting the plug head, the bottom of the mounting hole is provided with a limiting hole, and the center of the mounting hole is eccentrically arranged with the center of the limiting hole.

[0007] Through the above technical solution, when the stopper is inserted into the bottle mouth, the rotation axis of the stopper is consistent with the rotation center of the mounting hole; therefore, the limiting hole and the mounting hole are eccentrically arranged, and when the limiting hole matches the structure on the stopper, the rotation of the stopper relative to the mounting hole can be limited, thereby avoiding slipping between the stopper cover and the stopper when the bottle stopper is rotated; in addition, since the limiting hole is arranged at the bottom of the mounting hole, it is more convenient to observe the complete appearance of the limiting hole during production, which is leak-proof and is conducive to measuring the size of the limiting hole to prevent dimensional deviation.

[0008] Preferably, at least one limiting hole is provided in the mounting hole.

[0009] Preferably, an annular groove is provided in the bottle stopper body and on the inner circular surface of the mounting hole.

[0010] Through the above technical solution, the plug head portion can be stuck in the annular groove, making the connection between the two more stable and the plug head is not easily separated from the plug cover.

[0011] Preferably, one side of the annular groove is attached to the bottom of the mounting hole.

[0012] With the above technical solution, when the annular groove is attached to the bottom of the mounting hole, the edge of the limiting hole can be extended into the annular groove when necessary.

[0013] Preferably, the cross section of the limiting hole is circular.

[0014] Preferably, the cross-sectional shape of the limiting hole is semicircular.

[0015] Preferably, the cross section of the limiting hole is elliptical.

[0016] Preferably, the cross-sectional shape of the limiting hole is polygonal, and the corners of the limiting hole are transitioned through rounded corners.

[0017] Through the above technical solution, the polygonal limiting hole can limit the circumferential rotation of the plug relative to the plug, and the setting of the rounded corner transition facilitates the processing of the limiting hole, which is beneficial to controlling the yield of the limiting hole.

[0018] Preferably, the outer circumferential surface of the plug cover body is provided with rough lines.

[0019] Through the above technical solution, the rough pattern can better assist in gripping the bottle cap and prevent slipping.

[0020] The second object of the present invention is to provide a bottle stopper using the above-mentioned stopper cover, wherein the limiting hole can limit the circumferential rotation of the stopper head, thereby preventing the stopper cover and the stopper head from slipping when the bottle stopper is rotated.

[0021] The technical solution of the utility model is that a plug head is provided in the installation hole of the plug cover body, and a limiting block matching the limiting hole is provided on the plug head.

[0022] The technical effects of this utility model are mainly reflected in the following aspects:

[0023] 1. The limit hole can limit the circumferential rotation of the stopper, thereby preventing the stopper cap and the stopper from slipping when the stopper is rotated;

[0024] 2. It is more convenient to observe the complete appearance of the product, prevent leakage, and measure its size to prevent dimensional deviation and make the injection molding stage more stable;

[0025] 3. It can better help to grasp the bottle cap and prevent slipping. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp. Example 1

[0037] As attached Figure 1 The plug cover shown includes a plug cover body 1, which is provided with a mounting hole 3 for mounting a plug. A limiting hole 4 is provided at the bottom of the mounting hole 3, and the center of the mounting hole 3 is eccentrically arranged with the center of the limiting hole 4. When the plug is inserted into the bottle mouth, the rotation axis of the plug is consistent with the rotation center of the mounting hole 3; therefore, when the limiting hole 4 matches the structure on the plug, the rotation of the plug relative to the mounting hole 3 can be limited, thereby avoiding slipping between the plug cover and the plug when the bottle stopper is rotated; in addition, since the limiting hole 4 is provided at the bottom of the mounting hole 3, it is more convenient to observe the complete appearance of the limiting hole 4 during production, which prevents leakage and facilitates the measurement of the size of the limiting hole 4 to prevent dimensional deviation.

[0038] Among them, at least one limiting hole 4 is provided in the mounting hole 3. The limiting hole 4 can be one, two, or more. In this embodiment, a solution of a limiting hole 4 is selected for demonstration.

[0039] In addition, the cross section of the limiting hole 4 in this embodiment is circular, which is convenient for processing, observation and measurement. Example 2

[0040] The difference between the second embodiment and the first embodiment is that an annular groove 5 is provided.

[0041] As attached Figure 2 and 3 As shown, an annular groove 5 is provided within the bottle stopper body, located on the inner circumference of the mounting hole 3. The plug head can be retained within the annular groove 5, ensuring a more secure connection and preventing the plug head from being removed from the plug cap. The annular groove 5 can be positioned at a desired location along the axial direction of the plug cap. In this embodiment, one side of the annular groove 5 is positioned against the bottom of the mounting hole 3.

[0042] Here, when the annular groove 5 is attached to the bottom of the mounting hole 3 , the edge of the limiting hole 4 can be extended into the annular groove 5 if necessary. Example 3

[0043] The difference between the third embodiment and the second embodiment is that a rough pattern 6 is provided on the outer circumference of the plug cover body 1 .

[0044] As attached Figure 4 As shown, the outer circumferential surface of the plug cover body 1 is provided with rough lines 6. Example 4

[0045] The difference between the fourth embodiment and the second embodiment lies in the different shapes of the limiting holes 4 .

[0046] As attached Figure 5 As shown, the cross-section of the limiting hole 4 is semicircular. Example 5

[0047] The difference between the fifth embodiment and the second embodiment lies in the different shapes of the limiting holes 4 .

[0048] As attached Figure 6 As shown, the cross-sectional shape of the limiting hole 4 is an ellipse. Example 6

[0049] The difference between the sixth embodiment and the second embodiment lies in the different shapes of the limiting holes 4 .

[0050] As attached Figure 7 As shown, the cross-section of the limiting hole 4 is polygonal, and the corners of the limiting hole 4 are all rounded. The polygonal limiting hole 4 can limit the circumferential rotation of the plug head relative to the plug cover body 1. The rounded corner transition configuration facilitates the processing of the limiting hole 4 and helps control the yield of the limiting hole 4. Example 7

[0051] As attached Figure 8 and 9The bottle stopper shown utilizes the stopper cap of the above embodiment. A stopper head 2 is positioned within the mounting hole 3 of the stopper cap body 1. Stopper head 2 is provided with a stopper block 7 that mates with a stopper hole 4. The stopper cap can be made of wood or metal; the stopper head 2 can be manufactured separately and then assembled with the stopper cap body 1, or it can be integrally injection molded. In this embodiment, after the stopper cap is fabricated, the stopper head 2 is integrally injection molded within the stopper cap body 1. After the stopper head 2 is formed, a stopper shoulder 8 is also provided on the stopper head 2 that mates with the annular groove 5.

[0052] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
