FR2848798A1 - Device for opening reserve enabling heating sachet ingredient comprises two semi-rigid slides on each side of reserve base which when pressured open reserve allowing liquid to flow into sachet containing heating reagent - Google Patents

Abstract

The reserve (2) is sealed to a sachet (1) containing a heating reagent (9) which surrounds a sachet (7) containing an ingredient. On each side of the reserve base (3) are two semi-rigid slides (6) which enable it to be opened. When a pressure is exerted on the slides the reserve is opened and liquid flows from it into the sachet containing the reagent causing heat to be released.

Description

The present invention relates to a device for opening a reserve

containing a

  liquid, located at the upper end of a flexible sachet and allow this liquid to flow inside this sachet containing a heating reagent which itself envelops a second sachet containing a liquid or solid ingredient intended for immediate consumption by the user. The liquid located in the reserve flows into the first sachet, the envelope sachet, containing a heating reagent product and is interposed between the walls of the two sachets.

  The device according to the invention comprises a bag at the upper end of which is sealed a reserve obtained either by folding, or by welding, or by an "easy-to-open" bonding.

  This "easy opening" part is provided with two semi-rigid preformed bars, molded with the reserve or welded which allow to multiply the effort exerted by the user When he is going to open the reserve by pressing on the ends of these bars and causing thus the take-off of the lower part of the reserve thus liberating its content inside the envelope sachet.

  The sachet containing the ingredients and which is inside the envelope sachet is welded to the base of the latter by an "easy opening" glue so that its lower end is outside the envelope sachet.

  The lower end of the bag containing the ingredients may be provided with a thread 20 on which the user can adapt different servers; example of a pacifier The accompanying drawings illustrate the invention: FIG. 1 shows in section the device of the invention.

  Figure 2 shows in section a variant of this device.

  2 2848798 With reference to these drawings, the device comprises a reserve (2) which is obtained by sealing in the upper part of the envelope sachet (1) and welded at its ends (3) and (4).

  One end of this reserve (2) is welded by an "easy opening" bonding (3).

  On this zone (3) is heat-sealed or molded on each side a semi-rigid bar (6) The semi-rigidity of these bars (6) and the area of their fixings (3) are such that a low pressure exerted by the user on these bars (6) is multiplied It easily allows the opening of this reserve (2) and the flow of its contents.

  In the embodiment of Figure 1, the envelope sachet (1) is provided at its lower part with a passage sufficient to insert a sachet (7) containing ingredients, sealed to the envelope sachet (5).

  The bag (7) is largely inserted in the envelope bag (1) only one of the ends (8) is welded by an "easy opening" bonding and accessible from the outside by the user to easily release its contents .

  In the embodiment in FIG. 2, the bag (7) is provided at its end with a thread (10) making it possible to adapt different servers: example a pacifier (11) In this case, the envelope bag (1) is welded around the thread (12) A thin membrane (13) covers the bag (7) The introduction of the teat by screwing uncaps the membrane (13) and allows the contents of the bag (7) to flow.

  According to a variant not illustrated, the opening of the reserve (2) can be done by a simultaneous pressure on its two sides causing the bursting of its welded base, thus allowing the flow of its content in the envelope sachet (1) In this variant, the base of the reserve (2) is provided with an "easy opening" bonding, avoiding the use of semi-rigid bars. 3 2848798 According to a second variant not illustrated, the reserve (2) may be independent of the envelope sachet (1) and inserted inside the latter The user will then only have to firmly press the envelope sachet to cause "easy opening" of this reserve (2) thus causing the flow of its content in the envelope sachet (1).

  s By way of nonlimiting example, the envelope sachet will have dimensions of the order of 6 cm for the width, 4 cm for the thickness and 20 cm for the length.

  The device according to the invention is particularly intended for opening a reserve of liquid in an envelope sachet containing reactive heat-provoking products to heat the food content of a sachet and allow its instantaneous consumption.
