Improved lid for containers

Abstract

 Improved lid for containers that is made up from an inner body (1) that is fitted to a container on its outside part and by a second external body (2) in such a way that it encloses said inner body (1) by its external face, where the fitting of both bodies (1, 2) to each other is carried out by means of snap fitting, the said fitting together having being provided with a protrusion (3) on the inner edge of the inner body (1) that protrudes perpendicularly to the outside and which has a perimeter cavity (3A) into which a rib (4) is introduced which is an extension from the lower part of the external body (2).

Description

OBJECT OF THE INVENTION

[0001] The object of the present invention is an improved lid for containers that includes significant innovations and advantages compared to other arrangements of known lids.

[0002] More specifically the new invention refers to an improved lid for containers that includes an inner body that fits to the outer part of a container and a second body that fits to said inner body encasing it on its external face, the engagement of both bodies being carried out without additional elements.

BACKGROUND TO THE INVENTION

[0003] At the present time, the existence is known of a wide variety of containers made from plastics or synthetic resins that are used in the pharmaceutical and cosmetic industries and which have a main body and an upper lid, such as the container that is described in the Utility Model N° 9400649 that belongs to the same owner as this present applicant.

[0004] Said upper lid is usually formed by two bodies connected to each other, however, the union between the bodies is carried out by means of adhesion using adhesive products that are available in the market, and in so doing increase the manufacturing cost of the lid and also that of the whole packaging.

DESCRIPTION OF THE INVENTION

[0005] The present invention has been developed for the purpose of providing a lid for containers that solves the previously stated disadvantages, moreover, providing other advantages that will be clear from the description which is attached below.

[0006] The improved lid for containers of the present invention is of the type that has an internal body which is fitted to the container by its external part and a second body in the form of a casing fitted to said inner body encasing it by its external surface, and is basically characterised by the fact that the fitting of one part to the other is carried out by means of snap fitting, the inner body being provided with a protrusion on the underside and which includes a perimeter cavity into which a rib is introduced which is an extension of the external body.

[0007] Thanks to these characteristics a fixing of both bodies is obtained that avoids the use of additional elements such as special adhesive substances in such a way as to reduce the costs and manufacturing time of the lid itself.

[0008] In accordance with another aspect of the invention, the external surface of the cavity and the surface of the above mentioned rib that is in contact with said external surface have a milled surface finish. In this way the said two bodies are prevented from turning simultaneously when the user of the container turns the lid to open or close the lid on the container.

[0009] In a preferred embodiment of the lid, the inner body includes a threaded section that fits to a threaded section of the container in order to carry out the closing process of the container.

[0010] Other characteristics and advantages of the container lid object of the present invention will be come clear from the present description of a non exclusive preferred embodiment shown by way of example in the attached non limitative drawings, in which:

Figure 2 shows a detailed enlarged sectioned side elevation corresponding to a section of the fitting zone of the two bodies of the lid represented in the previous figure; and

Figure 3 shows a transversal section view along the line A - A in Figure 2 of the milled zone.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0012] The container lid object of the invention is intended for containers and tubs, for example, for use in the marketing of crèmes, cosmetic and similar products and is mainly made from an inner body (1) of a plastic material with a certain degree of flexibility that is fitted to a conventional container (not shown) on its outside and by a second external enveloping body (2) made out from the same or different materials, fitted to said interior body (1) so that it encloses it by its external face as and how can be seen in Figure 1. The fitting of both bodies (1, 2) to each other is carried out by means of snap fitting, the said fitting together having being provisioned by a protrusion (3) on the lower end of the inner body (1) that protrudes perpendicularly to the outside and which has a perimeter cavity (3A) into which a rib (4) is introduced which is an extension from the lower part of the external body (2).

[0013] The external surface of the stated cavity (3A) likewise the surface of the rib that is in contact with said external surface has a milled surface finish (6) (made up from a multitude of equidistant tabs), as and how they can be seen in figures 2 and 3, in such a way as to guarantee the immobility of one body against the other when the user makes a turning movement to open or close the container.

[0014] In this case the inner body (1) includes an internal threaded section (5) that fits to a threaded section of the container.

[0015] The details, shapes, sizes and other accessorial elements, likewise the materials used for the construction of the container lid of the invention can suitably be substituted for others that are technically equivalent and do not deviate from the essentials of the invention or the scope defined by the claims which are included below.

Claims

1. Improved lid for containers that is made up from an inner body (1) that is fitted on its outside part and by a second body (2) in such a way that it encloses said inner body (1) by its external face, characterised in that the fitting of both bodies (1, 2) to each other is carried out by means of snap fitting, the said fitting together having being provisioned by a protrusion (3) on the lower end of the inner body (1) that protrudes perpendicularly to the outside and which has a perimeter cavity (3A) into which a rib (4) is introduced which is an extension from the lower part of the external body (2).

2. Lid for containers according to Claim 1, characterised in that the external surface of the cavity (3A) and the surface of the rib that is in contact with said external surface has a milled surface finish.

3. Lid for containers according to Claim 1, characterised in that the inner body (1) has a threaded section (5) that is fitted to a threaded section on the container.
