Description

Technical field

The invention relates to a stopper for a container, for example a tube or bottle, with a chamber which is either empty or contains at least one active agent, for example a desiccant such as silica gel, activated carbon, a perfume or a preservative such as naphthaline, and / or the retaining system and, where applicable, the safety strap with the retaining device and / or the compression spring system, the guarantee strap with the retaining device being located in the downwardly directed cap extension and the compression spring system located at the bottom of the stopper and downwardly extending side and the top edge of the chamber is formed as a cap facing away from the stopper axis and adapted to the shape of the chamber, the cap preferably being formed as a circular element and in particular having a rectangular, square, circular, oval or elliptical cross-section. ez. The invention further relates to a method of making this plug.

BACKGROUND OF THE INVENTION

The plugs with or without the guarantee strip known from the prior art are in front view and in partial axial section in FIGS. 1 to 3.

FIG. 1 shows a first known stopper with a first first generation guarantee strip in which the first lid functions as a four-part carrier, namely a first chamber wall, a first compression spring, a first stud and a first warranty strap.

If the plug is intended to close a 27 mm tube, and when the first desiccant chamber has a volume of 2.56 cm ³ , the plug weighs 5.5 g without the first carton and without the first desiccant.

The individual parts, the first chamber wall, the first compression spring, the first olive and the first guarantee strap are all adjacent to each other and at certain distances from one another.

Such a plug can only be made in a very complicated injection tool. Removal from the mold necessarily requires 5 stages, thereby significantly prolonging the cycle time.

Another known plug with the second guarantee strap of FIG. 2 has a second compression spring disposed in the extension of the second tab.

Compared to the plug shown in FIG. 1, the second lid consists of only two parts.

This plug has a weight of 5.0 g for the above-described use, is simpler and easier to manufacture than the plug of FIG. Removal from the mold takes place in 4 stages.

Since the second compression spring is located in the extension of the second plunger, there is very little play between the outer dimension of the second compression spring and the inner diameter of the container opening.

Therefore, this plug must be inserted very accurately into the container opening, otherwise the second compression spring will be damaged.

The third known plug with the third warranty band has a cavity. With respect to this cavity, the lid part is moved downwards. This makes it possible to reduce the external dimension of the third compression spring compared to the previous second known plug while maintaining the advantage of demolding in 4 stages.

For the same use described above, this plug weighs only 3.5 g.

-1 CZ 290296 B6

Undesirable substances such as dust may collect in the cavity.

Due to the smaller diameter of the third chamber, it is necessary to increase the height of the third chamber by a length d correspondingly to maintain the usual volume of approximately 2.6 cm ^3. As a result, the core of the third compression spring is correspondingly reduced.

In the known plugs mentioned, the drying agent must be introduced in the direction of the respective compression spring, i.e. from the bottom. Consequently, the first carton, the second carton and the third carton must be introduced in the same direction and must be fastened with a collar.

In all the plugs described above, the first desiccant, the second desiccant and the third desiccant must be introduced in a separate operation. Spraying tools for the manufacture of these plugs are very complex and expensive to acquire and maintain.

The plugs described above consist of one piece. Obtaining a single piece by injection molding also requires that all parts be of the same material and have the same color.

French patent FR 1 090 874 discloses a plug with less functionality and for other uses. Neither the guarantee strap nor the compression spring system is described. This plug consists of one base body and a cap. The base body and the lid are removable for replacing the desiccant.

German patent DE 92 03 763.1 describes a plug for a container with a wolf part and a round tear-off ring. The clips are formed by ultrasound from the wall sections of the retaining ring. This plug is of one piece and is monochromatic. This plug is a first generation plug as described and illustrated in FIG. 1.

It is an object of the invention to overcome these drawbacks and to provide a stopper which can be manufactured by simple injection molding techniques. The object is to provide a plug in which the lid does not carry different parts, in which the side wall has several functions and whose weight is further reduced compared to the above-mentioned plugs.

The opening of the injection molding tool for the production of the main plug body should take place in two, at most three stages, in order to significantly reduce the cycle time.

The distance between the inner wall of the container and the outer dimension of the compression spring system should be such that the plug can be easily and easily fitted to the container without damaging the compression spring system.

The uppermost portion of the plug should have a regular and preferably transparent, void-free surface. The active zone of the compression spring system should always meet the stated requirements. The chamber should be capable of being filled with the active agent from above.

Another object of the invention is to provide a plug in which different parts are made of the same or different materials having the same or different color. To enhance the first-opening guarantee, the guarantee strip should preferably have a different color from the rest of the plug. A simple and inexpensive method of making the stopper should also be provided.

Yet another object of the invention is to assemble the individual parts at the time of filling with the active agent in a simple and inexpensive manner in the required number of stations in the same duty cycle and in the same fixture.

DETAILED DESCRIPTION OF THE INVENTION

Giant. 1 to 3 show, in front view and in partial axial section, plugs known from the prior art.

FIG. 1 shows a plug with a first first generation warranty strip 54.

In this plug, the first lid 50 functions as a carrier of four parts, namely, the first wall 51 of the chamber, the first compression spring 52, the first stopper 53 and the first guarantee strap 54.

If the plug is intended to close a 27 mm tube and when the chamber for the first desiccant 56 has a volume of 2.56 cm ³ , then the plug weighs 5.5 g without the first carton 55 and the first desiccant 56.

The individual parts, the first chamber wall 51, the first compression spring 52, the first latch 53 and the first guarantee strip 54, are all adjacent to each other and at certain distances from one another.

Such a plug can only be made in a very complicated injection tool. Removal from the mold necessarily requires 5 stages, thereby significantly prolonging the cycle time.

In Fig. 2 there is a plug with a second guarantee strap 60, a carton 65, a chamber wall 63 and a desiccant 66, in which the second compression spring 61 is located in the extension of the second tab 62.

Compared to the plug shown in FIG. 1, the second lid 64 consists of only two parts.

This plug has a weight of 5.0 g for the above-described use, is simpler and easier to manufacture than the plug of FIG. Removal from the mold takes place in 4 stages.

Since the second compression spring 61 is located in the extension of the second plunger 62, there is very little play between the outer dimension of the second compression spring 61 and the inner diameter of the container opening.

Therefore, this plug must be inserted very accurately into the container opening, otherwise the second compression spring 61 will be damaged.

FIG. 3 shows a plug with desiccant 76 with a third guarantee strip 70. This plug has a cavity 71. With respect to this cavity 71, the lid portion 72 is displaced downwards. This makes it possible to reduce the external dimension of the third compression spring 73 compared to the plug of FIG. 2, while maintaining the advantage of demolding in 4 stages.

For the same use described above, this plug weighs only 3.5 g.

In the cavity 71, undesirable substances such as dust may be collected.

To maintain a typical volume of approximately 2.6 cm ^{3 of the} third chamber, due to the smaller diameter of the third chamber, it is necessary to increase its height accordingly by a length d. As a result, the core of the third compression spring 73 is reduced accordingly.

In the plugs shown in FIGS. 1 to 3, the desiccant must be introduced in the direction of the respective compression spring, i.e. from below. Consequently, the first carton 55, the second carton 65, and the third carton 75 must be inserted in the same direction and must be fastened by screwing.

In all the plugs described above, the first desiccant 56, the second desiccant 66 and the third desiccant 76 must be introduced in a separate operation. Spraying tools for the manufacture of these plugs are very complex and expensive to acquire and maintain.

-5GB 290296 B6

The following table shows, inter alia, the radii of curvature r and the height h of the prior art plugs and one preferred embodiment of the plug according to the invention.

Table

The plug of FIG. Plug weight (G) Radius (mm) Height (mm) Chamber volume (cm ³ ) 1 5.5 ty 7,5 hi 7.25 2.56 2 5.0 ty 8 h ₂ 6.5 2.61 3 3.5 ty 7,5 h ₃ 8 2.83 4 3.05 r ₄ 12.4 114 3.55 3.4

This table shows that the weight of the plug according to the invention could be reduced by approximately 13% compared to the known plugs. These data also show that the volume of chamber 1 is significantly increased. Compared to heights hi to hj, the height l i is only about half. The radius of curvature of these is considerably increased compared to the radii of those of these. This implies that the compression spring system 6 has a significantly larger active zone at the same length of the individual helical springs.

This increase in the volume of the chamber 1 has the advantage that, with the same amount of active means 2 introduced, these active means 2 are in the unpressed state in the chamber 1. This makes it possible to maintain the flexibility of the side wall 8 in a direct condition and thus to guarantee the function of the sealing and / or retaining system 3.

The sealing and / or retaining system 3 is preferably in the form of an olive, grooves or slats are also possible.

This sealing and / or retaining system 3 must provide the required tightness to liquids such as water, moisture, dust or gases such as oxygen.

The lower part of the chamber 1 can be realized in two ways.

Either the lower part of the side wall 8 is formed as a flange 11 facing the axis of the plug. An element 12 is placed on top of this flange 11. This element 12 is connected to the flange 11 by gluing or welding. Snap fastening is also possible.

Alternatively, the bottom of the chamber 1 is formed as a bottom 13 of the chamber 1 with openings 14. A cap 12a may be placed on this bottom 13 of the chamber 1. This cap 12a can be attached to the bottom 13 of the chamber 1.

The element 12 or the bottom 13 with the openings 14 and optionally the cap 12a are arranged such that the active means 2 introduced into the chamber 1 from the top is retained and its effect can develop on the other side of said parts.

The number and shape of the apertures 14 are governed by the needs. Possible shapes of these openings 14 are shown in Figures 8a to 8f.

The compression spring system 6 normally comprises five individual helical springs and is connected to the skirt 11 or bottom 13.

In most cases, the compression spring system 6 has a cylindrical shape. The corresponding conical shape has the advantage of easier removal from the injection molding tool.

Since, in this conical shape of the compression spring system 6, the space between the individual helical springs is completely free, the correspondingly active zone of the compression spring system 6 increases.

-6GB 290296 B6

The upper edge of the chamber 1 is formed as a lid 7 diverted from the stopper axis and adapted to the shape of the chamber 1. This lid 7 preferably has the shape of a circular element.

The boundary zone 9 between the side inner wall 8b and the upper surface 7a is designed such that it can be connected to a closure 10 adapted to the size and shape of the chamber 1.

Depending on the type of active means 2, the boundary zone connection 9 must be chosen accordingly.

If a dry agent is introduced into chamber X, waterproof welding is selected. A possible type of such welding is shown schematically in Figs. 9a and 9b.

The closure 10 may be made of a transparent material. This has the advantage that it can be visually determined whether the active agent 2, such as a perfume or a preservative, is still present in the solid state. In addition, the transparent closure 10 allows tracking of the optical indicator.

It can be determined, for example, whether the desiccant, for example the blue gel, still has sufficient activity. It is also possible to observe, with the transparent closure 10, additionally introduced indicators into the chamber 1.

The appropriate thickness of the closure 10 is normally selected depending on the size of the plug. The thickness of the closure 10 may be approximately 1 mm.

In the downward extension 18 of the lid 7 there is a guarantee strip 4 with a catch device 5.

In order to simplify the first and all further opening of the container closed by the plug according to the invention, it is advantageous if the surface of the extension 18 facing upwards is not even and also not smooth. It is therefore preferable that the surface of the upstream extension 18 includes such auxiliary elements 20 that facilitate opening. Such auxiliary elements 20 may be, for example, grooves, notches, noses and the like.

These grooves may be arranged side by side and may be positive or negative. Generally, this surface is structured or embossed.

On the upside-down surface of the closure 10, there may be simple instructions for opening the container closed by the plug of the invention.

Advantageously, the extension 18 has at least one to four notches 19 which simplify the first opening.

If the main element, which includes, inter alia, the lid 7 and the guarantee strip 4 with the retaining device 5, is made in one piece, then these parts are of one material and have the same color. In this case, the guarantee strip 4 is connected to the main element by tear-off bridges, which represent the locations where the fracture is to be carried out.

It is advantageous if the main element with the lid 7 and the guarantee strip 4 with the retaining device 5 consists of two different parts which are produced separately and which have different colors. It has the advantage that the guarantee of first opening is visually better emphasized.

In this embodiment, the lid 7 and the guarantee strip 4 with the gripping device 5 are adjacent and mutually adapted edge zones 17. These edge zones 17 may be stepped or inclined. They can be joined together by gluing or welding.

The welds or glued joints may be continuous or preferably spot-welded. Welding can be thermal, ultrasonic or laser.

-7EN 290296 B6

The mechanical resistance of the two parts so joined is such that the joint is held when the plug according to the invention is placed on the container via the continuous outer projection 21, and that at the first opening the joint is easily broken by external force. This outer projection 21 may be in the form of a hook in axial section.

The retaining device 5 may comprise a number of clips, for example 2 to 6, with 6 clips being preferred. These clips are designed and positioned and adapted to the outer protrusion 21 such that removal of the plug according to the invention is prevented when the main element is connected to the guarantee strip 4.

Upon first opening, the retaining device 5 is engaged by the outer projection 21 and the separation of the main element and the guarantee strip 4 takes place along the edge zone 17.

The container may be a metal tube, for example of aluminum or a plastic tube, for example of polypropylene, polystyrene or polyethylene terephthalate (PET).

In the manufacturing process according to the invention, in the first operation, the respective individual parts required are manufactured individually in the injection molding tool. Thus, the guarantee strip 4 with the retaining device 5, the main element comprising the chamber 1, the sealing and / or retaining system 3, the compression spring system 6, the lid 7 and the extension 18 and the closure 10 can be manufactured individually.

If the main element has a flange 11, the element 12 is introduced in the second operation and joined or fastened accordingly. If, on the other hand, the main element has a bottom 13 with openings 14, the cap 12a can be introduced and possibly also fastened, thereby forming the lower part of the chamber L If desired, the active means 2 can now be introduced into the prepared chamber 1. the chamber 1 is closed by the closure 10.

If the guarantee strip 4 has been made as one piece with the retaining device 5, the individual piece must be connected to the main element. This occurs along the edge zone 17.

It is advantageous to perform this connection as a last operation in the manufacture of the plug according to the invention.

Industrial applicability

Lightweight plug, easy and inexpensive to manufacture, with larger active agent chamber volume and with screw springs with longer core.
