IPC 7 in 65 D 41/22

Bottle neck

The utility model relates to the design of containers, namely bottles intended for storage and use of cosmetic products and household chemicals.

The prior art various designs of threadless necks of vessels having external elements for connecting with threadless closures (caps, plugs, caps, etc.). Such devices include the structures described in patents: GB 1276756 and US 3592349, 3651972 and 5738231. Any of the indicated solutions can be taken as the closest analogue of the proposed utility model.

Known designs of the necks of the vessels do not provide the necessary reliability of their connection with the valves.

The technical result of the utility model consists in increasing the reliability of locking the shutter on the threadless neck of the bottle and in ensuring the versatility of the latter, namely the possibility of using the neck of the bottle with various types of caps, including those with a tear-off tab or hinged cover (such as a “flip-top”), as well as with spray devices (triggers).

The essence of the utility model is that, as in the closest analogue, the neck of the bottle contains elements located on the outside of its wall, designed to connect with locking devices. Unlike the closest analogue, these elements consist of: a sealing cone-shaped belt, which is made tapering to the edge of the neck and is located at a certain small distance from the edge of the neck, an annular groove-grip, the upper side wall of which is formed

the end part of the sealing girdle, the fixing protrusions made on the vertical part of the neck wall, below the annular groove, and the persistent conical shoulder, which is formed in the lower part of the neck wall and the surface of which tapers towards the shoulders of the bottle,

The bottle is mainly made of a polymer elastic material and has a cylindrical neck.

The annular groove may have a different profile, but a rectangular profile is preferred, while the locking protrusions can also be varied in shape, including they can be elongated along the neck wall and have a shape of a rectangle or parallelepiped in longitudinal section. The preferred number of such protrusions is 6.

All of the above features in their totality are aimed at achieving the above technical result, for example, the conical surface of the sealing girdle and thrust collar provides a more reliable connection with the internal elements of the lid (cap) including its warranty girdle. The locking protrusions serve to prevent rotation of the cap having a hinged cap and to fix the spray device on the neck of the bottle. An annular groove provides grip of the annular flange made on the inner surface of the lid.

The utility model is illustrated by the drawing, where Fig. 1 shows a neck with a part of a vial (general view) in Figs. 2a and b are variants of caps (sections).

The bottle 1 (Fig. 1) has a neck 2 with the following elements sequentially located on it from top to bottom: a sealing cone-shaped girdle 3, an annular groove - a grip 4, locking protrusions 5 and a persistent cone-shaped collar b, tapering to the shoulders of the bottle 1.

The upper side wall 7 of the annular groove 4 is formed by the end surface of the sealing band 3.

In Fig. 2a, one embodiment of the cap 8 is provided for sealing the bottle 1. The cap has a sealing element 9 on its inner surface that interacts with the sealing cone-shaped girdle 3 of the neck of the bottle, an annular collar 10 designed to be placed inside the groove 4, the warranty tab 11 and an annular collar 12, designed to interact with the persistent collar b of the neck of the bottle. The outer side surface of the lid 8 is provided with corrugations 13 for the convenience of hand grip.

On Fig shows a cap 14 with a hinged lid 15, designed to empty the contents of the bottle without removing the cap from the neck of the bottle. The specified cap has a sealing element 16, interacting with the girdle 3 of the neck of the bottle, the protrusions 17, designed to be placed inside the groove 4, the sealing element of the dispenser 18 and the loop 19 of the hinged cover 15.

The bottle is made of a polymer material suitable for storing cosmetics, which, due to its elastic properties, allows fastening of the shutter design to the neck of the bottle. At the same time, the bottle combines aesthetic qualities and technical capabilities, and also allows you to expand the range of such products.

The described design of the threadless neck of the vial will make it possible to obtain a tight connection with the lid plugging the vial, which will ensure the reliability of storage and transportation of cosmetic and other products in vials of various sizes from manufacturer to consumer
