Description

TAPE FOR RESEALING A PACK OF FLEXIBLE ARTICLES}

Various packaging methods exist for thin film products, especially moisture-containing tissues used for cosmetic, cosmetic and washing purposes. For the sake of simplicity, the following description focuses on moisture-containing tissue for human skin, especially for infant skin, but this description should be understood in light of the above description of the broader application of the invention.

Typically, moisture-containing tissue is stored in a dispenser or container that is discarded or reused. There is abundant disclosure in the prior art with examples of such dispensers or containers. For example, WO 96/37139 discloses a releasable dispenser for dispensing a plurality of water-containing products interleaved. Such dispensers include a housing having a recess with an orifice for removal of the product. A releasable flexible label is attached to the outer surface of the housing to completely cover the recess. EP 0 752 375 discloses an open device for a package formed from a tearable composite film. Straight cuts are formed across the film, and open tabs are welded or fixed on the outer surface of the film to cover the cuts. The open tab includes an adhesive portion and a gripping portion, which, when pulled, cause a pre-defined tear along the line coming from the end of the cut to allow access to the product stored therein. US Pat. No. 4,723,301 discloses a container having an access opening and a releasable seal device, wherein the releasable seal device consists of a closed flap whose one end region is fixed to the front side of the container and coated with a pressure sensitive adhesive. To be opened and released. A pair of cutouts are formed in the flap to define a pair of tabs integrally formed in one end area of the flap, and a pair of prevention holes are formed at the end of the cutout on the attachment line of the body of the flap to one end area of the flap; Both prevent the flap from tearing away from the container. The nonadhesive member is cut from the front side of the container to form an access opening and adhesively secured to the coated side of the flap. EP 0 590 708 B1 relates to a flow-pack for food products such as pasta. The flow pack consists of a sealed wrapper with a longitudinal fin with a cut-strip easy opening device designed to preclude the use of scissors or knives for opening. With this cut-strip, the wrapper is completely separated into two separate parts. The issue of resealing is not addressed.

In recent years, there has been a trend towards the use of reusable dispensers or containers in combination with refill packs to reduce the severity of disposable problems from an environmentally friendly point of view. In addition, research has shown that recent consumers have a tendency to buy a large number of products at a time, reducing the number of purchases. Thus, manufacturers have increased the number of discrete products contained in a single pack, resulting in a pack containing a relatively large amount of product. Thus, the market demand for refill packs, coupled with an increase in pack size, effectively reseals the packs of moisture-containing products in a completely satisfactory manner that ensures improved moisture retention and reduced water leakage. In addition, there has been a need for a high degree of user satisfaction and user trust due to the minimization of possible contamination levels from the external environment, in particular the robust nature of the tape does not pose a danger to infants in terms of inadvertent swallowing.

The present invention provides at least one tape that can be positioned on one surface of the pack to allow free access to the end of the pack from which the product is typically taken out, and also partially peels the tape for attachment to one of the opposing surfaces. It has been found that by providing at least one tape designed to make this possible, a simple and very effective solution to this need can be provided.

Summary of the Invention

The present invention focuses on a pack formed of a flexible material that includes two ends and first and second surfaces facing each other and surrounding two or more stacks of flexible articles. At least one of the first and second surfaces comprises at least one tape. The tape includes a functional portion, a grip portion, a longitudinal outer edge and a lateral outer edge and is located on at least one of the first or second surfaces to pack at least one of the stacks of flexible article. Free access to the ends of the and also allow partial peeling of the functional portion of the tape for effective attachment to one of the first or second opposing surfaces that reseal the pack after the at least one stack has been removed.

In one preferred embodiment of the present invention, one of the first or second surfaces corresponding to the area proximate to the outer edge of the functional portion of the tape has a weak area. The vulnerability zone includes at least one vulnerability line. In another embodiment of the present invention, the tape comprises essentially areas of weakness.

1 shows a pack 10 formed of a compliant material 11 surrounding two or more stacks 12 of flexible product 13. As used herein, the term "pliable" refers to a material that is flexible, such as plastics, foils, thin paper, or laminates. Such materials may be transparent or opaque and may include illustrations. In particular, FIG. 1 shows one preferred embodiment of the present invention in which the pack 10 contains two stacks 12 of moisture-containing tissue 13. The pack 10 essentially defines a rectangular volume. The pack 10 includes first and second surfaces facing each other (upper surface 14 and lower surface 15; One side 16 and the opposite side 17 and two ends 18, 19. The ends 18, 19 are sealed to each other according to methods well known to those skilled in the art (hereinafter referred to as those skilled in the art). Pack 10 may also include a fin seal, which may typically be located on top 14 or bottom 15, pack 10 being equally on sides 16, 17. It may include a pin seal.

At least one of the first or second surfaces 14, 15, 16, 17 includes at least one tape 20. The tape 20 includes a functional portion 21, a grip portion 22, a longitudinal outer edge 23 and a lateral outer edge 24 (see FIG. 4). The tape 20 may be made of a suitable material that is relatively tough and durable so that the user can pull the tape 20 firmly without tearing, deformation or damage upon multiple openings. It is common to use plastic materials such as polypropylene. In one preferred embodiment of the invention, the tape 20 is made of biaxially oriented polypropylene. The functional portion 21 of the tape 20 comprises an adhesive. Suitable adhesives are pressure sensitive adhesives supplied by 3M. As used herein, the term “gripping portion” refers to a portion of tape 20 that can be easily gripped by a user of a pack. The gripping portion 22 typically contains no adhesive, less adhesive material even if an adhesive is present, or simply includes a folded over portion of the functional portion 21 of the tape 20. The gripping portion 22 may include an illustration. In a preferred embodiment of the invention, the size of the tape 20 has a range of 1 cm to 5 cm in width and 5 cm to 10 cm in length.

The fragile lines may include scoring, cuts, cuts or perforations and may be formed by means known to those skilled in the art. 4 shows one preferred structure for the vulnerable zone 26. The tape 20 peeling operation by the user continues until separation reaches the vulnerable zone 26, where the first or second surface 14, 15, 16, 17 of the pack 10 in the vulnerable zone 26. Results in that a portion of the material of c) adheres to the underside of the tape 20. This serves to reinforce and enhance the function of the tape 20. The further peeling off of the tape 20 past the lateral outer edge 24 of the functional part 21, which is a failure, is prevented by this weak zone 26. In another embodiment of the present invention, only the tape 20 itself includes the vulnerable zone 26, which acts as a fixation. Vulnerability zone 26 includes at least one vulnerability line. The fragile lines can take any form, for the purposes of the present invention.

In another embodiment of the present invention as shown in FIG. 5, a fixing tape 30 is disposed under the tape 20. Thus, the fixing tape 30 lies on one of the first or second surfaces 14, 15, 16, 17 of the pack 10 and also adjacent to the functional portion 21 of the tape 20. The fixing tape 30 is partially folded back and adhesively attached to the functional portion 21 of the tape 20. Nevertheless, the fixing tape includes a function for adhesive attachment to one of the first or second surfaces 14, 15, 16, 17 of the pack 10. Typically, the fixing tape has a range of sizes ranging from 1 cm to 5 cm in width and 1 cm to 5 cm in length. In general, the fixing tape 30 is partially folded back in the range of 0.5 cm to 0.8 cm, preferably 0.75 cm, but not limited thereto, to allow satisfactory attachment of the tape 20.
