PACKAGING CASE FOR DISPOSABLE COMPRESSED TISSUE AND MANUFACTURING METHOD THEREOF
A packaging case for disposable compressed tissues is provided, which includes: a first accommodation portion which accommodates liquid; a second accommodation portion which has a stepped portion on the upper portion of the first accommodation portion so that the cross-sectional area of the second accommodation portion is larger than that of the first accommodation portion, and is partitioned from the first accommodation portion by a separable film which is thermally fused on the stepped portion by a thermal fusion operation, to thus accommodate tissues which have been compressed and dried; and a cover film which covers the upper portion of the second accommodation portion, wherein a bursting strength of the cover film is larger than that of the separable film when pressurized, so that the separable film is bursted before the cover film is bursted when pressurized.
The present invention relates to a packaging case for disposable compressed tissues, and more particularly, to a packaging case for disposable compressed tissues and a manufacturing method thereof, in which compressed tissues are packaged in large quantity more easily with liquid and a user can use the liquid-absorbed compressed tissues conveniently without spraying liquid by pressurization.
BACKGROUND ARTIn general, a disposable compressed tissue is made by compressing and molding a pulp material such as rayon. If predetermined liquid such as water is added to the disposable compressed tissue, the compressed and molded tissue absorbs the liquid and is restored into a previous state, that is, a before-being-compressed state, to thereby make a user simply use tissues conveniently.
However, to use the compressed tissues, water or functional liquid should be always equipped separately. Accordingly, to solve the above-described problem, the Korean Patent Application Nos. 10-2003-94198 on Dec. 20, 2003 (corresponding to Korean Patent Laid-open Publication No. 10-2005-48446 on May 24, 2005) and 10-2003-91984 on Dec. 16, 2003 (corresponding to Korean Patent Laid-open Publication No. 10-2005-60377 on Jun. 22, 2005), the Korean Utility-model Application Nos. 20-2005-17861 on Jun. 21, 2005 (corresponding to Korean Utility-model Registration No. 20-395866 on Sep. 7, 2005) and 20-2005-23428 on Aug. 12, 2005 (corresponding to Korean Utility-model Registration No. 20-0400633 on Nov. 1, 2005), and the Japanese Patent Application No. 2000-223676 on Jul. 25, 2000 (corresponding to Japanese Patent Laid-open Publication No. 2002-37350 on Feb. 6, 2002) were filed and disclosed.
Hereinbelow, a conventional packaging case for disposable compressed tissue (Korean Patent Application No. 10-2003-91984) will be described.

However, the upper member 10 and the lower member 20 are formed in a separate casing, respectively, and a separation guidance unit (not shown) should be separately formed in order to make it easy to attach the upper member 10 to and detach the upper member 10 from the lower member 20. As a result, expense and inconveniences of removal and recollection may increase. Further, there is a problem that the manufacturing processes thereof are not also accomplished in the block.
As illustrated in
However, it is burdensome that the liquid tube 60 or the liquid case 70 should be separately manufactured, and thus there is a problem that the production cost is increased. Further, when a certain amount of pressure is applied to break the liquid tube 60 or the liquid case 70 in the disposable tissue packaging case, the cover film 40 of the storage portion 50 may be damaged together.
In addition, in the case of the disposable tissue packaging cases shown in

In this case, although it is described that the intermediate film 810 is located across the inner walls of the case 800, it is not so easy to make the intermediate film 810 fixed to be located across the inner walls of the case 800. Accordingly, it is not so easy to mass-produce the disposable tissue packaging cases by automation, and it is difficult to efficiently use the disposable tissue packaging case. Even if the intermediate film is fixed across the inner walls of the case 800 using an adhesive, an adhesion area on either inner wall corresponds to the thickness of the intermediate film. As a result, the adhesion areas against aqueous solution are so small, and thus water-tightness cannot be secured against the aqueous solution.
Moreover, in the case that the disposable tissue packaging case is pressurized from the top and bottom of the case 800, internal volume in the case 800 is decreased, and internal pressure in the case 800 is increased. That is, the internal pressure in the case 800 becomes higher than the external atmospheric pressure (1 atm). For example, the internal pressure in the case 800 becomes 1.2 atm or higher. Accordingly, in the case that both the intermediate film and the cover film are broken, there is a problem that the high-pressure aqueous solution is sprayed out as if water-outburst happens when a balloon filled with water is pressurized and bored. This phenomenon is called a balloon effect.
The Japanese Patent Application No. 2000-223676 on Jul. 25, 2000 (corresponding to Japanese Patent Laid-open Publication No. 2002-37350 on Feb. 6, 2002) discloses a conventional “double-type separable portable tissue case” 6 as illustrated in
In this case, the cover film 7 and the intermediate film 8 should have a substantially equal tensile force. Accordingly, the cover film 7 and the intermediate film 8 may be torn off from the case 6 by the F and G direction tensile forces. However, the respective lengths and bonded positions of the cover film 7 and the intermediate film 8 differ from each other. As a result, there is a problem that the operation is frequently mal-functioned. Further, since an extended portion 8a of the intermediate film 8 is closely adhered to the inner wall of the case 6, and the end 8b of the intermediate film 8 is closely adhered to the upper surface 6c of the case 6, the right and left portions of the intermediate film 8 are of an asymmetrical structure in view of a three-dimensional structure. Accordingly, it is not so easy to mass-produce the tissue cases by automation, and the production cost thereof is increased.
DISCLOSURE OF INVENTION Technical ProblemTherefore, in order to supplement the shortcoming of the conventional art, it is an object of the present invention to provide a packaging case for disposable compressed tissues in which a liquid accommodation space and a tissue accommodation space are integrally molded and formed in a single accommodation member, and simultaneously a separable film is also formed therein by automation, to thereby accomplish curtailment of a manufacturing cost, elevation of an operational efficiency and reduction in number of recollected cases after use.

The present invention provides a packaging case for disposable compressed tissues, comprising: a first accommodation portion which accommodates liquid; a second accommodation portion which has a stepped portion on the upper portion of the first accommodation portion so that the cross-sectional area of the second accommodation portion is larger than that of the first accommodation portion, and is partitioned from the first accommodation portion by a separable film which is thermally fused on the stepped portion by a thermal fusion operation, to thus accommodate tissues which have been compressed and dried; and a cover film which covers the upper portion of the second accommodation portion, wherein a bursting strength of the cover film is larger than that of the separable film when pressurized, so that the separable film is bursted before the cover film is bursted when pressurized.
The present invention also provides a method of manufacturing a packaging case for disposable compressed tissues, comprising the steps of: molding a synthetic resin material to form a first accommodation portion which accommodates liquid, a second accommodation portion which has a stepped portion on the upper portion of the first accommodation portion to thus accommodate tissues which have been compressed and dried; thermally fusing a separable film on the stepped portion after having accommodated liquid in the first accommodation portion; and covering the upper portion of the second accommodation portion after having accommodated tissues in the second accommodation portion which have been compressed and dried, wherein a bursting strength of the cover film is larger than that of the separable film when pressurized, so that the separable film is bursted before the cover film is bursted when pressurized.
Mode for the InventionHereinbelow, a packaging case for disposable compressed tissues according to a preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings.
As illustrated in
It is preferable that the liquid accommodation portion 110 in the accommodation portion 130 is of a cylindrical or hexahedron shape. A volume of the liquid accommodation portion 110 in the accommodation portion 130 has a little larger than that of the tissues 102 so that the amount of the liquid 101 can be accommodated as much as the amount which can be absorbed by the whole tissues 102. Further, the upper side of the liquid accommodation portion 110 in the accommodation portion 130 is opened by bursting of the cover film 150.
Thus, the tissue accommodation portion 120 is integrally molded and formed in the upper side of the liquid accommodation portion 110, so as to have a stepped portion 110a, that is, in a stepwise manner as shown in
The separable film 140 is a film which is thermally fused on the stepped portion 110 (see
Meanwhile, the position of the liquid accommodation portion 110 may be exchanged with that of the tissue accommodation portion 120. The liquid in the liquid accommodation portion 110 may be a functional aqueous solution for cleansing or nutritional moisturizing.
Here, in order to make a bursting strength of the cover film 150 larger than that of the separable film 140, it is preferable that the separable film 140 is a soft aluminum thin film and the cover film 150 is a thermally heat treated hard aluminum thin film. Meanwhile, the separable film 140 is made by coating only an adhesive on an aluminum thin film, but the cover film 150 is made by coating a synthetic resin film and an adhesive film on an aluminum thin film in order to heighten a bursting strength. Alternatively, in order to obtain a difference in the bursting strengths between the separable film 140 and the cover film 150, the thickness of the cover film 150 may be relatively thicker than that of the separable film 140.
Thus, the separable film 140 whose bursting strength is relatively weaker than that of the cover film 150 has been bursted by the external pressurization before the cover film 150 is bursted. Accordingly, the compressed tissues 102 absorb the aqueous solution to lower the increased internal pressure in the packaging case. Then, the cover film 150 is bursted or torn off by the continuously applied external pressurization, to enable a user to take out and use the liquid-absorbed tissues 102.
As described above, since the separable film 140 is bursted earlier than the cover film 150, the above-described balloon effect can be prevented.
