Description

 The present invention relates to a device making it possible, on packages requiring a single sealed envelope or two separate envelopes, the first of which is waterproof, to use a pouring spout while guaranteeing, before opening, the seal of the single envelope or the sealing of the first envelope.

 The food packaging used for foods of the “breakfast cereal” type or for chocolate powder, is traditionally presented as follows: for the needs of preservation, the food is contained in a first waterproof envelope of plastic or other This first envelope is placed in a second, non-waterproof envelope, generally made of cardboard. The consumer must open the box. in cardboard from the top, then open the waterproof envelope, and finally pour the food into a container These packages have several defects. First of all, two envelopes must be opened consecutively. If the cardboard box does not pose any particular problem , the waterproof envelope can be placed on it. Due to its necessary solidity, it can be difficult to open and require the use of a sharp object. Furthermore, the opening made in the waterproof envelope is generally irregular and the flaps of the opening of the cardboard box being troublesome, this results in poor control of the payment.

Very often the consumer pours too much product or pours a part of it aside. During the pouring operation part of the product heats up from the first envelope and ends up at the bottom of the cardboard box. To consume the product in its entirety it You must then remove the first envelope in order to recover it at the bottom of the second.When it is a product like powdered chocolate which is very fine escapes through the interstices, it can be messy. rightly recommend closing the packaging after use.

This recommendation is rarely observed because it is tedious to roll the top of the first envelope and close the cardboard flaps.

 The device according to the invention overcomes these drawbacks. To solve the problem of controlling pouring, the use of a retractable spout of the com type carrying two small lateral sides perpendicular to a large frontal side and located on the the upper part of one of the vertical sides of the package is the most suitable solution.

 Packages with a pouring spout of this type located on a single, non-waterproof envelope are known.

 Packages making a spout of this type cooperate covered with a capsule and located on a second envelope, with an opening made on the first sealed envelope, are known, but the seal thus obtained is relative because moisture can penetrate into the opening of the first envelope by the permeable parts of the second envelope not covered with the capsule.

 Packages with a pouring spout of this type located on a first non-waterproof envelope entirely covered with a second waterproof envelope are known, but they are neither very practical because they require the use of a sharp object in order to release the spout, neither very aesthetic.

 More rigid packages with two non-distinct envelopes, the cover of which is provided with a spout of another type cooperating with an opening made by the user in the first envelope, are known, but they are not adapted to the criteria of lightness. , packaging size or simplicity, required by certain products.

 How to make cooperate a spout of the type comprising two small lateral sides perpendicular to a large frontal side and located on the upper part of one of the vertical sides of a second envelope, with an opening made by the user on a first envelope perfectly waterproof before opening, so that the lateral sides of the spout are positioned outside this opening, whatever the open or closed position of the spout? Or how to make cooperate a spout of this type located on the upper part of one of the vertical sides of a single, waterproof envelope with an opening. practiced by the user in this envelope, so that the lateral sides of the spout are positioned outside this opening, whatever the open or closed position of the spout? These are the problems to be solved and it is on their so lution that the invention carries.

 The device according to the invention is designed for packaging comprising either a single waterproof envelope or a first waterproof envelope inserted in a second non-waterproof envelope. Throughout the description of this patent, the terms unique waterproof envelope "and" second envelope "denote the same object, except for the seal.

 The invention comprises a single sealed envelope or second envelope comprising on the upper part of one of its vertical sides a quadrangular opening over which is fixed a pouring spout foldable on itself in bellows along the line A / B.

 According to the version with two envelopes, the second envelope contains a first sealed envelope possibly comprising a quadrangular opening covered with an obstruction means.

 In this version the user proceeds as follows: having opened the spout he sees the first envelope or the means of obstructing its opening. He then practices by tearing an opening in the second envelope or he removes the obstruction means from its opening. After use, it closes the spout thus ensuring sufficient protection for the product for the duration of use.

The invention will be better understood from the description which follows, made with reference to the accompanying drawings by way of indicative examples only, in which:

 Referring to FIGS. 7,4 and 3 and according to the two-envelope version, it can be seen that the first sealed envelope 6 is inserted into a second envelope 1. The second envelope 1 is fixed to the first 6 at the internal periphery 9 of its quadrangular opening 2 made in the upper part of one of its vertical sides The user then makes an opening in the envelope 6 by tearing.

According to a preferred embodiment of the envelope 6 and with reference to Figures 2 and 5, we see that the first envelope 6 has on the upper part of one of its vertical sides a quadrangular opening 7 covered with a removable capsule 5 provided of a gripping end 3 When the user removes the capsule 5 he releases the opening 7 provided with a dimension sufficient for the easy flow of the products The opening 7 and the capsule 5 are of a dimension slightly less than 1 'opening 2.The two envelopes 1 and 6 are fixed to each other at the level of the respectively internal 9 and external 8 peripheries of their openings 2 and 7 located opposite.

 Referring to Figure 8 we see that the capsule 5 has a gripping end 3 accessible from the outside of the package, fixed on its lower horizontal side, folded back on itself parallel to its vertical sides, and a length greater than these.

 Referring to Figure 6 we see that according to a variant of the casing 6, the opening 7 is delimited by a line of quadrangular weakness 11 formed in the thickness of the material, of a dimension slightly less than the opening 2, and covered by a removable border 12 having a gripping end 13. When the border is removed it brings with it the material surface of the envelope 6 corresponding to the opening 7. The arrangement and the size of the the gripping end 13 of the border 12 is identical to that of the gripping end 3 of the capsule 5.

 In this version with two envelopes, the envelope 1 must be secured to the sealed envelope 6 at least at the internal periphery 9 of its opening 2.I1 it is understood that it can also be secured to the envelope 6 over its entire surface, in a way forming a second sealed envelope 1 formed of two thicknesses of different materials, except at its slot 17 and / or its opening 2.

Referring to Figures 1,10 and 11 we see that according to the main feature of the invention, applicable to versions with one or two envelopes, the single waterproof envelope or second envelope I has fixed over its quadrangular opening 2 a spout pourer 14 and 21 whose lateral sides 15 and 27 fold in on themselves in a bellows along the line A / B while positioning themselves during the closure outside the opening 2 above
Referring to Figure 1 we see that according to a first embodiment, the spout 14 has a fixing lug 20 located along its three sides, and a tongue 16 for holding in the closed position located on the edge upper of its large front side and intended to penetrate into a horizontal slot 17 formed on the casing 1 above the opening 2 at a slight distance from the fixing zone 9.

 Referring to FIG. 9 and in the version with a single sealed envelope 1, it can be seen that the opening 2 and the slot 17 are covered with a removable capsule 18 provided with a gripping end 19 whose arrangement and dimension are identical to those of the gripping end 3 of the capsule 5. The pouring spout 14 then has on the internal face of its tongue 16 a bonding point on the casing 1 intended to hold it in the closed position before removing the capsule 18.

 Referring to FIG. 11, it can be seen that according to another embodiment, the pouring spout 21 comprises a fixing frame 22 on the casing 1, a gripping end 23 situated on the upper part of the front side and intended for its opening, a protuberance 25 located on the upper edge of the frame 22 or on the upper part of the front side and intended to keep it in the closed position.

 Referring to FIG. 12 and in the version with a single sealed envelope I it can be seen that the opening 2 is covered with a removable capsule 29 provided with a gripping end 30 whose arrangement and dimension are identical to those of the gripping end 3 of the capsule 5.

In both embodiments the spout 14 and 21 is preferably made of flexible plastic, in the open position and in a single injection molding operation. The lateral sides 15 and 27 are thinner than the front side. The junction of the lower edge 31 and 26 with the tab 20 or the frame 22 acts as an elastic hinge and the material of which it is made has a natural tendency returning the spout 14 and 21 to the open position in which it was molded. The fold line A / B is materialized by a line of reduced thickness of the material of the lateral sides 15 and 27
The lateral sides 15 and 27 can also have a natural tendency to return to their initial molding position, and in this case the fold line A / B is not materialized.

According to a variant of the version with two integral envelopes over all or part of their respectively internal or external surface, the surface of the first envelope 6 obstructing the opening 2 of the first envelope l is fixed to the internal face of the spout 14 and 21, so that when the spout is open it causes the opening of the first casing 6.

 The device according to the invention can be provided on any of the vertical or even horizontal sides of the packaging, without thereby departing from the scope of the invention.

 The invention is obviously not limited to the form of execution and to the dimensions described and shown, which may undergo modification of detail without departing from the scope of the invention. It is for example of course understood that the openings of the two envelopes or the pouring spout may be of circular shape.

 The device according to the invention is particularly intended for the packaging of all food products or not, which are poured by fraction into a container and the conservation of which, before opening, requires the use of a single sealed envelope or of two envelopes of which the first is waterproof.
