Description

Bag to pack bread.

Object of the invention

The present invention relates to a bag to pack bread, which provides essential novelty features and notable advantages over known media and used for the same purposes in the current state of the technique.

More particularly, the invention proposes the
development of a bag, obtained by joining and folding two different die-cut sheets of paper or similar, of which one is preferably transparent and the other is opaque, intended for preferential packaging of bread or even other food products, and obtained by mutual application of both sheets and folded by premarked lines for the purpose of forming a container container provided with an access mouth that can be closed by folding a flange provided with maintenance means in the closed condition.

The scope of the invention is is obviously included within the industrial sector dedicated to the manufacture of paper bags and containers or similar, and  more particularly those for bread and other packaging food products.

Background and summary of the invention

It is known to everyone in general the fact that Bread sticks usually show up at points of sale arranged in drawers or shelves, each of them introduced into the inside of an individual paper bag or similar of one size more or less adjusted to the loaf of bread. The consumer picks up the product directly from the shelf, and transport it from the establishment of sale to or address or place of consumption in the inside the paper bag in which you purchased it.

This form of presentation, although it is evident which provides a certain degree of hygiene and protection to consumer product, it is no less true that it also presents some disadvantages worthy of being taken into account, and that they derive essentially from the fact that the bags in which they Presents the product are normally open, so suffer from an insufficient level of hygiene, given that, on the one hand, through the mouth of the bag they can penetrate unwanted products inside the bag and be deposited on bread or other consumer products, and on the other part, such a bag does not prevent any consumer have direct access to the consumer product, and can manipulate it unduly with the risks and inconveniences that it entails

Taking into account the associated inconveniences to bread bags and the like currently used in the prior art, the present invention has been proposed as main objective is to provide a bag with which guarantee a level of protection and hygiene appropriate for the bread or other product that is housed in it. This goal has been fully achieved through the bag that is going to be described in the following, and whose characteristics main are collected in the characterizing portion of the attached claim 1.

In essence, the bag for packing bread is conforms from two flat sheets of paper or similar, advantageously die cut according to the desired final appearance, of which one is transparent and the other is opaque. The application of one upon the other obtaining the bag or container, allows the bread or other food housed inside can be displayed easily by the consumer through the closed area with the transparent sheet In addition, the mentioned transparent sheet incorporates, in the area of the mouth, an adhesive means incorporated by the inner face, protected by a strip of plasticized paper or other easily removable material, located in a position facing a recess formed in the opposite edge provided by the opaque nature sheet, of such that the folding of the upper strip allows closing the mouthpiece by folding an upper transverse strip, and fix the adhesive means on the outer surface of said opposite opaque sheet. In this simple way, with a mere folding operation prior introduction of bread or product to contain, it is possible to close the mouth of the bag, providing thereby adequate protection of the packaged product and eliminating the possibility that a consumer can access and manipulate unduly said product.

Brief description of the drawings

These and other features and advantages of the invention, will become more clearly apparent from the detailed description that follows in a preferred way of embodiment, given by way of illustration only and not limiting, with reference to the accompanying drawings, in the that:

Figure 1 is a flat representation, in plant, of the two sheets used for the formation of the bag of the invention;

Figure 2 is a view slightly in perspective, of the bag obtained from both sheets of the Figure 1, and

Figures 3 and 4 illustrate paths seen in elevation of the finished bag of Figure 3, in the bag condition  closed and taken by each of the respective faces of the bag.

Description of a preferred embodiment

As mentioned above, the detailed description of the preferred embodiment of the invention will be carried out in what follows with the help of the attached drawings, through which the same numerical references to designate equal parts or similar. Thus, attending first to Figure 1, you can appreciate the flat representation of two sheets of paper or similar, indicated in general by reference numbers 1 and 2, whose die cut corresponds to a development that allows the formation of a bag for bread or other food after application and bonding by gluing one sheet over the other, as will see later.

Looking at sheet 1, made preferably from a sheet of opaque nature, it appreciate that it responds to a general rectangular configuration, symmetrical with respect to the major axis, which at one end shows a  wide recess delimited by a transverse edge the, and that at the opposite end it presents a flange or skirt 1b. To both sides, and according to the longitudinal direction, the sheet shows the formation of folding lines 3, 4, 5 that occupy a strip marginal of predetermined width.

For its part, sheet 2 is of configuration rectangular in plan, preferably of a transparent nature (intermittent scratching has been performed on its surface to show such condition), and presents the particularity of incorporating an adhesive means 6 incorporated in a position centered on one of its ends, next to the corresponding transverse edge, counting this adhesive means with an easily removable protection 7 in The moment of its use.

With both starting sheets 1, 2 configured as they are represented in Figure 1, it will be understood that the formation of a bag or container can be achieved in a very simple way with the mere application of a sheet on the another, and linking both by pasting. This situation is clearly shown in Figure 2, where the bag has been obtained after folding the marginal stripes of the sheet 1 delimited by said fold lines 3, 4, 5, with the superimposition of the 4th most extreme strip over the marginal zone corresponding transparent sheet 2, as a tab bonding. The projection 1b of the sheet 1 appears bent about itself, to support against. sheet 2 and close the bag by the lower end. On the other hand, the recess makes it a transverse strip of the sheet 2 protrudes, which is going to constitute the closing tab of the upper mouth of the bag, while the marginal strips folded successively, they constitute a formation on each side as a bellows, which allows the bag to admit inside products Different thicknesses and sizes.

As stated above, the mouth of the bag is closed by folding the portion transverse of transparent sheet 2 that exceeds the height of the edge the delimiter of the recess of the sheet 1. This situation is represented in Figures 3 and 4, in which shows the appearance of the closed bag seen from both sides. In Figure 3 shows the opaque face of the bag, having been folded down the protruding upper portion of sheet 2 on said sheet 1, keeping the mouth closed by application and bonding of the adhesive medium 6 on this sheet opaque, after removal of protection 7.

On the opposite side (position corresponding to Figure 4, the space between both marginal strips 4a of glued is occupied by transparent sheet 2, so that the consumer can always appreciate the contents of the bag closed, but without the possibility that the food contained inside.

It should be noted that the incorporation of the adhesive medium linked to the transparent sheet 2 does not imply practically any delay or investment of time as regards the production process, since the removal of the protector 7 and the folding of the upper strip to close the mouthpiece, it is a very simple and very fast operation that, nevertheless, guarantees the maintenance of the set in hygienic conditions much more appropriate for the type of products to which it is expected to apply the bag
developed by the invention.

It is not considered necessary to make the content of this description for a subject matter expert can understand its scope and the advantages derived from the invention, as well as develop and implement the object of the same.

However, it should be understood that the invention has been described according to a preferred embodiment thereof, so which may be subject to change without implying any alteration of the basis of said invention, being able to affect such variations, especially the shape, size and / or the manufacturing materials of the different components that They integrate the set.
