Abstract

Receptacle or bottle or container or package or tube, automatically reclosable, for any solid, liquid, gas, paste, characterized by a device closed by a slot which is sealed when at rest, situated in any portion and made of plastic or elastic material and swaged so as to be enlarged during seizing by a deformation inducing the opening of the slot and enabling to pour the content of the bottle or receptacle before retaking automatically its permanent sealing position. The device is applied to any receptacle, bottle, container, package or tube containing any solid, liquid, paste.

Description

The present invention belongs to the category of devices for opening and closing a container (or bottle, packaging, container or tube) containing any liquid, any solid, any gas, any powder or paste without the need for remove or replace a shutter on the opening of the container (the shutter system closing alone and being an integral part of the container, but can be built and attached to any existing receptacle).

The opening and closing of a container is traditionally done by removing or putting back a shutter (this represents effort and time) and when it is forgotten, the content can be spilled or spoiled. Earlier patents CILIBKHTI 2,937,795, COONEY US 1,889,693 included two or more crossed slits and because of the shape of the deformation could not be hermetic or remain it as a result of the acquisition of a permanent deformation which at l 'usare condemns the conservation of the product and condemns the viability of the invention unfit by degradable products.

The patents 3,110,335 US AKTONIUS and 3,176,743 US BUNDY cannot be built in a single blow molding or injection molding operation and are complex. Their structural elements make them unsuitable and not airtight for use in liquids and pastes as mentioned by HELLSTROM in a later patent for the ANTONTUS patent. US Patent 3,595,446 HELLSTROM includes a reinforcement ring which is complex and is not necessary in my invention; nor can it be constructed in a single blow molding or injection molding operation.

It was not easy for a professional to shorten the path leading to these complex implementations to collect a part of a whole that simplifies the problem and makes it viable by its simplicity, and its real hermeticity in common use. In fact, the object of the invention is not to replace plugs for transport security and existing inviolability which can be adopted without particular difficulties.

This simplification makes the invention technically simple to carry out and economical.

However, in certain particular cases, a plastic wire or else an adhesive patch sealed on the slot can ensure its inviolability; the user by pulling one or the other ensures the loosening of the two lips.

In another improvement, a partially removable tongue in the same way can allow, after the first use, to be reapplied by friction and to allow the user a perfect skinning; likewise for a jumper remaining attached to the receptacle by an extension. fig. 5, fig. 6

The device according to the invention is characterized by a single slot made hermetic by various characteristics:

it is curvilinear in the horizontal plane 11 this promoting the opening of the lips,

-it is oblique in the vertical direction fig2 to ensure a large contact surface between the two lips,

-view in section, the flexible wall comprising the slot is bi-concave, for by contact pressure to oppose the flow of the product, -the edge of each lip can be increased on the internal side and up to the edge of the slot to ensure a large contact surface and without thickening the entire surface of the wall which is expensive. 21 It includes a receptacle or receptacle or tube closed by a a slot 11 at its top or laterally, or in any part whatsoever in the rest state; the device is made of elastic materials or molded plastics, to react thanks to their elasticity or also to ancillary systems for the same purpose described below, during direct or indirect gripping support, by a deformation causing a protruding movement allowing the opening of the slot by deformation of the two lips to be able to pour the content. Fig8.9 The support tension of the two lips can be, but not necessarily improved by the following improvements: 1 / pins and reinforcements bulges, ribs12

2 / or rods, or tongues, activated like a spring 13 or not or plastic springs or jumpers with inverted supports Fig 4 integral with the structure or non-integral and attached, oriented in all planes. When the user has separated the two lips, the inclusion of a single plastic rod 13 and stamped in one of the edges of the slot will increase the effect of return spring when closing.

For tube receptacles, it is possible to produce a single flexible wall on the obturator side which comes crashing down on the opposite edge of the more or less ririd tube and which, by design, has a lug area against the leg support, flexible wall by calculating this counter-support location the flexible wall will operate as a doseor V system. Fig 7

3 / support zones are indirectly supported, that is to say that they actuate other zones, themselves triggering the opening Figures 8 - 9 - 10 - 11

As soon as the user support stops, the shutter alone returns to its original permanent shape closed by the slot.

The edges of the opening or two or more openings are hermetic by any existing mechanical, physical, or chemical adhesion effect for example and are in position:

- either edge to edge, horizontal, roof, concavity,

- either by overlapping from one edge to the other in the same shapes as edge to edge.

A / Either an edge is embedded in a double wall Fig. 3 opposite female hollow or a male press button in a female press button

B / Either that this embedding arrangement is reproduced several times, two or three times in lamination in different planes, in series of male edges coming to interpenetrate in a series of double female walls,

C / Or that the two edges of the slot are made contiguous by two edges of Velcros (registered trademark) is an example of a possible product

D / Or made hermetic by a slightly sticky or slightly adherent coating, Liner, Silicone, plastic, composite on the edges retaining its properties after several uses, so that the automatic reclosing movement recreates a hermetic seal, or a capillary seal at each time.

The Scel-o-frais product (registered trademark) is an example of a possible product.

These different processes can be combined with each other for the same purpose of a contiguous or hermetic closure. Methods A, B, C, D as hermeticity methods can be sufficient in themselves without being associated with stampings for closing containers, bottles, containers with incorporated shutter.

Alternatively, the container, bottle or container can present an elastic tension of the material exactly opposite to the first dies tending to the separation in the area of the opening As soon as a cap or other safety means ensuring the closing of the edges is removed, the rest of the opening is done automatically. tick of the propensity of the material helped by aros ribs included or reported to return to its initial equilibrium position which, there is characterized by an open position of the edges Fig.12 This variant would find applications, in particular to facilitate the opening of all cans of food or all boxes, containers, containers, bottles.

The closure would be made by an effort of the user to bring the edges of the opening closer and possibly to reattach them by one of the means described or by any means of attachment or attachment in order to allow or not, depending on the product, a possible re-use.

In another improvement, the opening may be blocked in the open position if necessary for the user. This blocking can be achieved for any blocking, retaining, locking, hooking device, incorporated or not, inside or outside the bottle, tending to keep the two edges of the opening apart. The device is made of a semi-rigid elastic material made of plastic, silicone, rubber, aluminum, flexible metal or any material meeting the elasticity and plasticity characteristics, applicable for part or all of the container.

One of the embodiments of the device is by a blow molding or plastic injection molding operation:

-the slot can be made afterwards by an operation incision,

- The slot can be pre-cut, so as to be carried out during the molding operation, or blowing-injection, having a weak area of 2 to 2/10 th of mm which will open on the first press, or mechanically or of the first user.

By another improvement, if the outer wall is in a rounded shape, or then covered with a soft plastic film of contact, the dispcritif can be used as an applicator for cosmetic cream, shaving, sunscreen.
