The present invention relates to a container (1) suitable for containing and dispensing wipes, the container (1) comprising external and internal surfaces and the wipes being made from a substrate, wherein the container (1) comprises a portion sample of said substrate, wherein the portion sample is attached onto at least one external surface of the container (1).

TECHNICAL FIELD

The present invention relates to a container suitable for containing and dispensing wipes. More specifically, the invention is directed to a container comprising a portion sample made of the same material as the wipes contained within the container, wherein the portion sample is attached onto at least one external surface of the container.

BACKGROUND

Containers suitable for dispensing wipes, and in particular pre-moistened wipes, are known in the art. Flexible containers comprising pre-moistened wipes are, for example, described in WO91/04920 whereas rigid containers suitable for dispensing pre-moistened wipes are disclosed, for example, in U.S. Pat. No. 5,791,465.
Both flexible and rigid containers known in the art generally comprise a dispensing opening, typically situated on the upper surface of the container, and a lid or sealing device, which can usually be repeatedly opened and resealed. Known containers therefore provide good sealing and satisfactory dispensing of the contained wipes.
However, known containers do generally not allow the consumer to inspect and see the appearance of the wipe products before purchase (i.e. in the point of sale). Typically, the known containers would need to be opened so as for the potential consumer to see and touch its content, i.e. the wipes. This is of course not ideal since opened containers on the shop shelves will detrimentally affect their aesthetic appearance. More dramatically, in the case of containers for pre-moistened wipes, the action of opening and re-opening may lead to pre-maturate evaporation of the lotion applied onto said pre-moistened wipes. Partial solutions have been proposed e.g. in US 2004/0094437, wherein the wipe packaging is provided with a window capable of displaying the product enclosed within the container. Alternatively, the aspect of the enclosed wipes may be graphically represented in one of the external surfaces of the container so as to permit identification of its content. However, none of the known wipe containers provide the consumer with the possibility to touch and feel the texture of the wipe which is intended to be purchased. This is particularly appreciable when the wipe is provided with some very soft touch or a three-dimensional structure on it, as described e.g. in US 2003/0228813.
It is therefore an objective of the present invention to provide a container suitable for containing and dispensing wipes which not only allows the potential user to inspect the appearance of the wipes but which also permits touching and feeling the texture of the wipes contained within the container.
It has now been found that this objective can be met by providing a container 1 suitable for containing and dispensing wipes, the container 1 comprising external and internal surfaces and said wipes being made from a substrate, wherein the container 1 comprises a portion sample of the substrate, and wherein the portion sample is attached onto at least one external surface of said container 1.
Advantageously, the portion sample according to the preceding invention may be attached onto the container 1 using any labeling machine/technique commonly known in the art.
Commonly known consumer wipes, such as dry or pre-moistened hard-surface cleaning wipes, are typically made from a fabric-type substrate. The substrate material is usually chosen to provide good cleaning lotion absorbance and sufficient integrity. However, it remains substantially flexible, fibrous and porous. Those flexibility, fibrous-like and porosity characteristics render the substrate materials difficult to process when trying to directly attach a portion of said substrate material onto any surface, in particular the surface of a wipe-containing container.
According to a specific embodiment of the present invention, it has further been found that the above processing problem is solved when the portion sample for use in the present invention is laminated with a supporting material thereby forming a laminate piece 4, and wherein the laminate piece 4 has an effective stiffness.

SUMMARY OF THE INVENTION

The present invention relates to a container 1 suitable for containing and dispensing wipes, the container 1 comprising external and internal surfaces and the wipes being made from a substrate, wherein the container 1 comprises a portion sample of the substrate, and wherein the portion sample is attached onto at least one external surface of the container 1.
In another embodiment, the present invention encompasses a process of manufacturing an improved container 1 suitable for dispensing wipe, wherein the process comprises the steps of (a) providing a container suitable for containing and dispensing wipes, wherein the container comprises external and internal surfaces and said wipes are made from a substrate; (b) laminating a portion sample of the substrate with a supporting material thereby forming a laminate piece 4, wherein the laminate piece 4 has an effective stiffness; and (c) attaching by means of an adhesive the laminate piece 4 obtained in step (b) onto at least one external surface of the container.
The present invention is further directed to a process of presenting wipes contained within a container 1, wherein the process comprises the steps of (a) providing a container suitable for containing and dispensing wipes, wherein the container comprises external and internal surfaces and said wipes are made from a substrate; and (b) attaching a portion sample of the substrate onto at least one external surface of the container.

In a highly preferred embodiment of the invention, the wipe is a pre-moistened wipe comprising a substrate having a plurality of abrasive means applied thereon, i.e. a plurality of discrete three-dimensional structure made of an abrasive material applied thereon. Suitable abrasive wipes are described e.g. in co-pending EP Patent Application N^o05075308.
Portion Sample
In the context of the present invention, it has been surprisingly found that by providing a container 1 which comprises a portion sample of the substrate which the wipes contained within the container 1 are made of, and wherein the portion sample is attached onto at least one external surface of the container 1, the user or purchaser is not only allowed to inspect the appearance of the wipes but he may also touch and feel the texture of the wipes contained within the container 1.
The user may therefore fully appreciate and inspect the quality of the wipes which are enclosed within the container 1 that he is intending to purchase, without the need to open or affect the integrity of the container 1.
The portion sample for use in the present invention is made of the same material (i.e. substrate) as the wipes contained within the container 1.
In a preferred execution, the portion sample would have exactly the same appearance and texture as the wipes which are contained within the container 1 and onto which said portion sample is attached. This implies that in a preferred execution, the portion sample for use in the present invention has the same colour, texture and is provided with same three-dimensional structures (if applicable) or aesthetic features as the wipes contained within said container 1. In this preferred execution, the container 1 according to the present invention provides the purchaser with the highest informative value.
In the context of the present invention, the portion sample may be of any shape including, but not limited to round, oval, square, triangle, rectangle, rhombus, crescent, star, stripe, grid line, undulating line, circular dot, heart, hexagon, diamond, and combinations thereof. Preferably, the sample portion is of round shape.
In a preferred execution, the portion sample is attached by means of an adhesive and preferably onto at least the top panel of the container 1 according to the invention.

Advantageously, suitable adhesives will not detrimentally affect the texture and/or the colour of the portion sample when applied onto it.
In the preferred execution where the container 1 of the present invention comprises pre-moistened wipes, the portion sample attached onto the container 1 is preferably not loaded with a lotion, but may be.
The portion sample for use in the present invention is preferably attached onto at least one external surface of the container 1 by means of a permanent adhesive. Suitable permanent adhesives are those know in the field. Preferred adhesives are for example acrylic-based permanent adhesives.
Laminate Piece
In a preferred embodiment of the present invention, the portion sample is laminated with a supporting material thereby forming a laminate piece 4.
Suitable lamination processes for use herein are well known in the art of labeling. Typically, the portion sample is laminated with the supporting layer by means of an adhesive. Suitable adhesives for use in the lamination process are identical to those described above for attaching the portion sample onto at least one external surface of the container 1.
In the context of the lamination process, suitable adhesive may be applied as a coating layer either on the integrality of the portion sample surface or at selected areas of it. Preferably, suitable adhesive is applied onto the entirety of the portion sample surface. In an alternative execution of the present invention, suitable adhesive is applied at selected locations, preferably on the central zone, of the portion sample surface. This particular embodiment allows the purchaser to inspect and feel both sides of the wipes he is intending to purchase.
Suitable supporting materials are those well know by the person skilled in the art of labeling. As a minimal requirement, suitable supporting material shall be fully compatible with the above-mentioned adhesive. Preferably, the supporting material is a flexible material, such paper or plastic films. More preferably, the supporting material is a polymeric film. In a highly preferred execution of the present invention, the supporting material is a polypropylene film. Suitable supporting materials will not detrimentally affect the texture and/or the colour of the portion sample when applied onto it. In contrast and in a preferred aspect, the supporting material for use in the present invention will help enhancing the touching and feeling of the portion sample and may be used to provide additional aesthetic benefits to the portion sample attached onto the container 1 of the present invention.
According to a preferred embodiment of the present invention, the laminate piece 4 herein is provided with an effective stiffness. By “effective stiffness”, it is meant herein that the laminate piece 4 is provided with a stiffness which is suitable for said laminate piece 4 to be dispensed from a regular labeling machine. Suitable regular labeling machines are described e.g. in EP-B1-0 677 013.
Stiffness of the laminate piece 4 is measured, at 23° C. under 50% relative humidity, according to a modified Standard Test Method D 4032, as described in the Test Method Section hereinafter. Stiffness measurement may be performed using the Instron 6021 Dynamometer manufactured by Instron.
In a preferred embodiment of the present invention, the stiffness of the laminate piece 4 is of at least 3N, when measured according to the Test Method described herein. Preferably, the stiffness of the laminate piece 4 ranges from 3N to 20N, preferably from 4N to 15N, more preferably from 5N to 10N, even more preferably from 5N to 7N, most preferably from 5.5N to 6.5N.
The Applicant has surprisingly found that when selecting stiffness of the laminate piece 4 to be of at least 3N, preferably from 3N to 20N, more preferably from 4N to 15N, still more preferably from 5N to 10N, even more preferably from 5N to 7N, and most preferably from 5.5N to 6.5N, the corresponding laminate piece 4 is provided with suitable stiffness for it to be easily dispensed from a regular dispensing machine in the context of a regular product labeling process. Suitable dispensing/labeling apparatus and processes are described e.g. in EP-B 1-0 677 013.
Without wishing to be bound by theory, it is believed that laminate pieces not fulfilling the above stiffness requirements will lead to obtain laminate pieces not easily processable or releasable from commonly used label-applying machines. As a consequence, such non-suitable laminate pieces may only be dispensed manually onto the corresponding containers forbidding therefore any large scale industrial production.
It has been further discovered that the laminate pieces 4 suitable for use in the context of the present invention will provide the user with a pleasant and realistic touching/feeling experience. Moreover, suitable laminate pieces 4 will not detrimentally affect conformability properties exhibited by flexible containers 1 according to the present invention.
The laminate piece 4 for use in the present invention is preferably attached onto at least one external surface of the container 1 by means of a permanent adhesive. Suitable permanent adhesives are those well known in the field. Preferred adhesives are for example acrylic-based permanent adhesives.
Preferably, the laminate piece 4 is attached onto at least the top panel of the container 1 according to the invention. Containers 1 may additionally comprise laminate pieces 4 on the bottom panel and/or on the opposing side panels. In the particular execution where the container 1 comprises an opening- and closing-cover label, the laminate piece 4 is preferably attached onto the cover-label.
Process for the Manufacture of an Improved Container
In a further embodiment of the invention, it is provided a process of manufacturing an improved container 1 suitable for dispensing wipe, wherein the process comprises the steps of (a) providing a container suitable for containing and dispensing wipes, wherein the container comprises external and internal surfaces and said wipes are made from a substrate; (b) laminating a portion sample of the substrate with a supporting material thereby forming a laminate piece 4 wherein the laminate piece 4 has an effective stiffness; and (c) attaching by means of an adhesive the laminate piece 4 obtained in step (b) onto at least one external surface of the container.
Step (c) of the above process may be performed manually or in an automated manner according to techniques well known in the art. Those will therefore not be described in further details herein. Preferably, the step of attaching by means of an adhesive the laminate piece 4 onto at least one external surface of the container 1, is performed using a regular label-applying station as described in EP-B 1-0 677 013. Typically, the surface of the laminate piece 4 comprising the supporting material is coated with a permanent adhesive layer which is preferably non-sticky until appropriate activation. Suitable permanent adhesives for attaching the laminate piece 4 onto the container 1 are for example acrylic-based permanent adhesives.
Process of Presenting Wipes
The present invention is further directed to a process of presenting wipes contained within a container 1, wherein the process comprises the steps of (a) providing a container suitable for containing and dispensing wipes, wherein the container comprises external and internal surfaces and said wipes are made from a substrate; and (b) attaching a portion sample of the substrate onto at least one external surface of the container.
In a preferred execution of the present invention, the portion sample is attached onto at least one external surface of the container 1 by means of an adhesive.
Containers 1 according to the present invention provide the user or purchaser with an improved informative value with respect to the wipes which are contained within the container 1. A further advantage of the containers 1 according to the present invention is that they increase the advertising value of containers for wipes commonly known in the art and provide the consumer with a unique buying experience.

- Scale Convenient type
  3. Procedure

Test sample should be conditioned in a climatic room for not less than 6 hours before testing.
The plunger 5 and the holed platform 6 are respectively fixed to the upper cross head and the lower clamp of the tensile tester.
3.1. Sample Preparation
A circular sample 8 of 60 mm diameter is cut out and put it over the holed Platform.
The plunger end is set 10 mm above the sample surface.
3.2. Test Procedure
The test procedure is as indicated in ASTM D 4032.
Parameters are set as follows:

- Gauge length 10 mm
- Crosshead speed 500 mm/min
- Measurement length 20 mm
  4. Calculations

The peak load (N) of each sample is reported.

EXAMPLES

Example 1

An abrasive wipe was made using a commercially available carded hydro-entangled nonwoven substrate of 58 g/m²basis weight containing 60% synthetic fibers and 40% absorbent fibers. The applied polymeric material is polypropylene supplied by Basell under the trade name Moplen HF 1005. The polymeric material was applied by a gravure printing process as described in EP-A1-1 262 531.
The abrasive wipe is then laminated with a bi-axially oriented, gloss polypropylene film in a conventional manner using an acrylic-based intermediate adhesive coating. The obtained laminate is then coated on its polymeric film surface with an acrylic-based permanent adhesive material. The overall stiffness of this laminate piece (4) has been determined to be of 6.1 N, as measured according to the Test Method described herein.
The laminate piece (4) coated with the acrylic-based adhesive is then attached to a regular wipe-containing flexible packaging according to the method described in EP-B1-0 677 013.
