Embodiment Construction

[0025] figure 1 The shown container 1 comprises a body 2 ; closed at one end by an end wall 3 , at the other end of which is a neck 4 ; a free edge 5 of the neck forms an aperture 6 . The neck 4 has a thread 7 on its outer surface. As will be seen in detail below, the thread 7 can be connected to a corresponding thread on a locking device 10 ( Figure 2A 11) in cooperation. In this embodiment, the locking device 10 includes an inner part 12 placed within an outer cover 13 . The internal part 12 can be fixed in the outer cover 13 by bonding, welding or pressing buttons. The inner part 12 comprises a transverse wall 14 whose edges are bent at 90° to form a side skirt 15 . On the inner surface of the side skirt, there is a thread 11 . The side skirt comprises two diametrically opposed grooves 24, 25 located near the area where the transverse wall 14 and the side skirt 15 intersect. The two grooves will be described in more detail later.

Abstract

A closure has a first screw thread (11) capable of cooperating with a second screw thread formed by a container intended to receive the closure. An elastically deformed part (28, 31) is capable, when the first (11) and second screw threads are engaged, of keeping the closure bearing elastically on the container in at least one direction oriented radially with respect to the closure, so as to improve the holding and working of the closure on the container.

Description

technical field [0001] The present invention relates to a closure in the form of a threaded closure which can be placed on and removed from a container, in particular in the form of a carafe, bottle, jar or other shape. The present invention is particularly suitable for use as a closure for jars such as encapsulating cosmetic and skin creams. Background technique [0002] In the field of cosmetics, especially in the field of skin care oils, it is more common to use large mouth glass bottles. Typically, these jars are capped with a plastic cap that includes a thread that can engage a corresponding thread on the outer surface of the jar near a hole defined by a free edge of the jar. Cooperate. [0003] One of the many problems encountered with this form of packaging is caused by too large a gap between the jar and its plastic cap. This gap is basically due to the very large manufacturing tolerances of the threads on the jar. Such gaps can cause problems with airtightness, ...
