Description

Technical Field

[0001] This utility model belongs to the field of bottle cap technology, and in particular relates to a container bottle cap and packaging bottle. Background Technology

[0002] like Figure 1-2 As shown, in order to prevent the contents of the container from leaking, a gasket 101' is usually attached inside the cap 1'. The container 5' and the cap 1' are connected by threads. The inner diameter of the thread 4' inside the cap 1' is larger than the inner diameter of the gasket 101'. The thread 4' is used to hold the gasket 101' in place so that it does not fall off. However, the assembly of the container bottle gasket with this structure is relatively troublesome, and the assembled gasket is severely warped and deformed around its periphery. Utility Model Content

[0003] In view of this, the present invention provides a container cap and packaging bottle, in which vertical ribs fix the gasket, thereby preventing the gasket from warping and deforming around the periphery.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: The first aspect of this utility model provides a container bottle cap, the container bottle cap including a cap body and a gasket attached to the inner wall of the cap body, the cap body extending toward the container bottle having a skirt, the inner wall of the skirt having a plurality of vertical ribs provided near the gasket, the maximum distance between the edges of two vertical ribs in opposite positions away from the inner wall of the skirt being less than the maximum distance of the gasket.

[0005] In a preferred embodiment of this utility model, the cover is circular, and the inner diameter of the cylinder formed by the edge of the vertical rib away from the inner wall of the skirt is smaller than the diameter of the gasket.

[0006] In a preferred embodiment of this utility model, the container cap is threadedly connected to the container bottle, the inner wall of the skirt has an internal thread, and the inner diameter of the internal thread is larger than the diameter of the gasket.

[0007] In a preferred embodiment of this utility model, the inner diameter of the cylinder formed by the edge of the vertical rib away from the inner wall of the skirt is smaller than the inner diameter of the thread of the internal thread.

[0008] In a preferred embodiment of this utility model, the vertical rib is connected to the inner wall of the skirt in a circular arc transition.

[0009] In a preferred embodiment of this utility model, the length of the vertical rib along the axial direction of the container cap is 3-8mm.

[0010] The second aspect of this utility model provides a packaging bottle, including a container cap and a container bottle according to any of the above embodiments, wherein the container cap and the container bottle are detachably connected.

[0011] Because of the adoption of the above technical solution, this utility model has the following advantages and positive effects compared with the prior art: The container cap provided by this utility model includes a cap body and a gasket attached to the inner wall of the cap body. After the container bottle and the cap are assembled, the gasket can seal the bottle mouth. The cap body extends towards the container bottle and has a skirt. The inner wall of the skirt is provided with vertical ribs near the cap body or the gasket. The vertical ribs are ribs protruding from the inner wall of the skirt. The maximum distance between the vertical ribs in relative positions is less than the minimum distance of the gasket. Thus, the vertical ribs can hold the gasket in place on the inner wall of the cap body. Since the vertical ribs and the gasket are connected by a point interference fit, the probability of the gasket warping after assembly is reduced. Attached Figure Description

[0014] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the container cap and packaging bottle proposed in this utility model. The advantages and features of this utility model will become clearer from the following description.

[0015] The first aspect of this application provides a container cap, such as... Figure 3-5 As shown, the container cap 1 includes a cap body 101 and a gasket 2 attached to the inner wall of the cap body 101. The cap body 101 extends toward the container bottle and has a skirt 102. The inner wall of the skirt 102 is provided with a plurality of vertical ribs 3 near the gasket 2. The maximum distance between the edges of two vertical ribs 3 in opposite positions away from the inner wall of the skirt 102 is less than the maximum distance between the gasket 2.

[0016] The shape of the cover 101 can be circular or rectangular, without any restrictions. The vertical ribs 3 are ribs protruding from the inner wall of the skirt 102. The maximum distance between the edges of two opposite vertical ribs 3 and the inner wall of the skirt 102 is [value missing]. Assuming the cover 101 is circular and the gasket 2 is circular, the multiple vertical ribs 3 on the inner wall of the skirt 102 form a cylinder. The maximum distance between the edges of two opposite vertical ribs 3 and the inner wall of the skirt 102 is [value missing]. Figure 3 In the diagram, L represents the maximum distance between the gasket 2 and the inner wall of the skirt 102. Assuming the cover 101 is rectangular, the gasket 2 is also rectangular. Consequently, the multiple vertical ribs 3 on the inner wall of the skirt 102 form a rectangle. The maximum distance between the edges of two opposing vertical ribs 3 and the inner wall of the skirt 102 is the longest side of the rectangle formed by the vertical ribs 3, and the maximum distance between the gasket 2 and the inner wall of the rectangle is the longest side of the rectangle. The maximum distance between the edges of two opposing vertical ribs 3 and the inner wall of the skirt 102 is less than the maximum distance between the gasket 2, thus allowing the vertical ribs 3 to attach the gasket 2 to the inner wall of the cover 101, preventing the gasket 2 from falling off. Furthermore, the vertical ribs 3 and the gasket 2 are connected by a point interference fit, reducing the likelihood of the gasket 2 warping or buckling after assembly.

[0017] More preferably, the cover 101 is circular, and the gasket 2 is also circular. Then the skirt 102 is cylindrical. The vertical ribs 3 along the axial direction of the inner wall of the skirt 102 form a cylindrical inner diameter L away from the edge of the skirt 102. The cylindrical inner diameter L is smaller than the diameter of the gasket 2, so that the vertical ribs 3 can hold the gasket 2 in place and prevent the gasket 2 from falling off.

[0018] More preferably, the container cap 1 is threaded to the container bottle 5, and the inner wall of the skirt 102 has an internal thread 4. The inner diameter of the thread 4 is larger than the diameter of the gasket 2. Therefore, when the gasket 2 is assembled, the internal thread 4 will not affect the gasket 2, thus avoiding deformation of the gasket 2. The assembly of the cap 101 and the gasket 2 is relatively convenient.

[0019] After the existing bottle cap 1 is threadedly assembled with the container bottle 5, in order to prevent the bottle cap 1 from being squeezed and deformed, the wall thickness of the bottle cap 1 needs to be relatively large. In this embodiment, preferably, the inner diameter L of the cylinder formed by the edge of the vertical rib 3 away from the skirt 102 is smaller than the inner diameter of the thread of the internal thread 4. That is, the cylindrical diameter L formed by the vertical rib 3 is smaller than the inner diameter of the thread of the internal thread 4. In this way, the gap between the vertical rib 3 and the thread of the container bottle 5 is smaller, which can better position the container bottle 5 and thus prevent the bottle cap 1 from becoming crooked or tilted.

[0020] Furthermore, the vertical rib 3 is connected to the inner wall of the skirt 102 by a rounded transition, which can prevent excessive stress at right angles from causing cracks.

[0021] Furthermore, along the axial direction of the container bottle 5 cap 1, the length of the vertical rib 3 is 3-8mm. The longer length of the vertical rib 3 provides better fixation for the gasket 2. Assuming that the gasket 2 is slightly tilted, since the gasket 2 and the vertical rib 3 can be interfered at the point of contact, the longer length of the vertical rib 3 can also prevent the gasket 2 from falling off.

[0022] The second aspect of this utility model provides a packaging bottle, including a container bottle 5 cap 1 and a container bottle 5 as described in any of the above embodiments, wherein the container bottle 5 cap 1 and the container bottle 5 are detachably connected.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
