Description

[Technical Field]

The present invention relates in general to a blister package for simultaneously housing, in a single package body, a case which is configured to insertably and withdrawably store contents for facilitating portability and storage, and a cartridge type contents which is insertably and withdrawably stored and used inside the case, and more particularly, to a blister package where a case accommodation part for accommodating the case and a separate content accommodation part which is filled with contents are simultaneously molded on a molding sheet such that when each accommodation part is sealed with a covering film and a cutting line is provided on an edge part of the content accommodation part, therefore, during use, only the content accommodation part may be independently torn off to be stored inside the case, or may be opened and inserted into the case. Therefore, a packaging process for a case and a manufacturing process for a cartridge package container or a refill package container are completable in a single process, and as a result, a reduction of a packaging process may lead to improved productivity and reduced manufacturing cost.

[Background Art]

Typically, a blister package is a type of package method as a thermoplastic plastic film or a sheet, and is a method in which contents are put in a swollen portion of a container body, which is made of a plastic laminated molding sheet molded by pressure forming or vacuum forming in a shape which roughly resembles a product desired to be packaged, and then, only a flat flange part of the container body is adhered with a covering film made of a paper or a plastic laminated film, by heat-sealing, a high frequency wave, an ultrasonic wave, etc., which is widely used in packaging of food, daily necessities, goods, industrial products, refined chemicals, liquid cosmetics, and the like.
Meanwhile, the blister package body as above is designed to be disposable or consumed short-term depending on the type of contents. Also, for easily spoiled contents, the contents are not stored in a separate case, but sold to be used once. In a case of contents which are repeatedly used over a relatively long-term period and has low spoilage potential such as a wax type solid perfume, a diffuser, or cosmetics, etc., the contents are used in a structure capable of opening for usage and then closing again while stored in a plastic or metal case for facilitating portability or storage.
Further, for some products, in many instances, a cartridge-type package body is stored in a metal, a plastic, a ceramic, or a glass container, or content from a refill package body is put in a container to be used, thus facilitating portability and storage. To distribute and sale such a product, a container and a cartridge package body or a refill package body may be stored again in a paper case, a transparent plastic case, or a metal, a plastic, a ceramic, or a glass container, or a transparent blister package which shows the cartridge or the refill container, and then may be sold.
In this way, a case and a content package body that has already been formed by a blister package method become a set through a blister package.
For making a conventional blister package body, first, a process in which contents are packed by the blister package through a molding sheet provided with a container part and a covering film is required (forming a container filling contents sealing a cover). Secondly, a process which stores the content package body which completed packaging into a separate case again, and thirdly, a process in which the case storing the content package body is secondarily packed by the blister package through a molding sheet provided with a container part and a covering film are required (forming a container inserting into a case sealing a cover).
In a conventional packaging method, a packaging process for the case and a packaging process for the content package body are made by separate processes which require two blister packaging processes, thereby causing a rise in manufacturing cost and a fall in productivity due to the increase in the packaging processes.
In addition, since a conventional package body only accommodates the case and the content package body which is filled with contents on sale, for example, it is common that a separate package is delivered to a consumer in order to introduce a product sample for checking the consumer's feedback about a prototype in development, a not-for-sale product which completed development, or a conventional product for promoting sales to the consumer. Also, most blister packages are not provided with additional functions and structures to accommodate samples. In this case, generation of cost for delivering a sample is unavoidable.
Therefore, it is difficult to ensure accuracy, efficiency, and diversity of feedback due to difficulties in asking for various opinions and having a wide range of sample distributions by using the method which distributes separate samples to a certain group of testers in order to check the consumers feedback about a prototype in development or a not-for-sale product which completed development.
Document US 3083821 describes a blister package comprising a lower layer of heat-sealable plastic, shaped to provide more than two differently sized accommodation parts, whereby one of the said accommodation parts is filled with an epoxy resin; a catalyst for the resin and spatula or applicator elements are contained in the other accommodation parts; the top surfaces of the lower layer around and between the accommodation parts being arranged in substantially the same plane such that an upper covering film type layer of flexible heat-sealable plastic can be attached for sealing the filled accommodation parts.
Document WO 97/02192 describes a blister pack, comprising at least a first and second parallel rows of blisters, and of the type in which a base foil formed with blisters is connected to a substantially flat lid foil. Between the first and second rows of blisters there is provided an intermediate part having at least one folding line parallel to the first and second rows of blisters. The blister pack is foldable along the folding line, and the blisters of the first row are offset relative to the blisters of the second row, so that, after folding, the blisters of the two rows engage between each other; moreover perforation type cutting lines are comprised for enabling separation of individual blister packs.

[Technical Problem]

The present invention, in order to solve the aforementioned problem, provides a blister package in which only a content accommodation part may be independently torn off to be stored inside the case when in use, or a content accommodation part having refill contents therein may be torn off and opened to be stored in the case for usage. The present invention is directed to providing a blister package which simultaneously houses a refill or cartridge type content package container and a case accommodating the same to improve productivity and reduce manufacturing cost by a reduction of a packaging process which completes a packaging process for a case and a manufacturing process for a cartridge or refill package container in a single process.

[Technical Solution]

To achieve the above object of the present invention, there is provided a blister package as defined in claim 1 which is simultaneously molded to have a case accommodation part accommodating a case and a separate content accommodation part being filled with contents such that the content accommodation part has a broken line on an edge part thereof to enable the content accommodation part to be independently torn off while each accommodation part is sealed with a covering film.
Further, the present invention is additionally configured to have a sample content accommodation part which is capable of packaging sample contents of a prototype in development or a not-for-sale product which completed development on the molding sheet.

[Advantageous Effects]

According to the present invention as described above, a case may be withdrawn and a content accommodation part may be torn off to be stored inside the case when a blister package body is opened. Or the content accommodation part may be opened and inserted into the case to be used. Therefore, a packaging process for the case and a manufacturing process for a cartridge package container are completable in a single process, and as a result, a reduction of a packaging process may lead to improved productivity and reduced manufacturing cost.
Furthermore, as a prototype in development scheduled to be released, a not-for-sale product completed development, or a sample for promoting sales is accommodated in a product for sale to unspecified individuals, a consumer may become aware of features of the sample in advance, thereby increasing the consumers expectation and taking an advantageous position in a decision of product choice. A variety of feedback may be received regarding the sample, which helps improve the product quality of the products on the market. Unlimited distribution range of samples ensures accuracy, effectiveness, and diversity of the feedback.

[Modes of the Invention]

Hereinafter, exemplary embodiments of the present invention will be described in detail. However, the present invention is not limited to the exemplary embodiments disclosed below, but can be implemented in various forms. The following exemplary embodiments are described in order to enable those of ordinary skill in the art to embody and practice the invention.
The present invention will be described hereinafter in detail.
A blister package includes a known structure in which a package body of the present invention is formed on a piece of a molding sheet, a case accommodation part to accommodate a case having a cover is provided, and the molding sheet has a covering film attached on a back side thereof.
Here, the blister package includes each of a content accommodation part which is formed on the molding sheet to be filled with and accommodate contents, a cartridge or refill cutting line which is formed along a lower edge part of the content accommodation part, provides a flange part on the content accommodation part, and also selectively enables an individual separation and tear-off on the molding sheet and the covering film so as to form an independent cartridge or refill package container, and is configured to have a notched part for connection at one part thereof, a sample content accommodation part formed on the molding sheet in order to be filled with and accommodate sample contents of a prototype in development or a not-for-sale product which completed development, a sample notched line which is formed on the molding sheet and selectively enables the sample content accommodation part to be individually separated and torn off on the molding sheet and the covering film so as to form an independent sample package container, and a projecting part for opening guidance which protrudes from the molding sheet and allows a portion of the cartridge or refill cutting line to pass through the inside so as to form a separating space between the molding sheet and the covering film in a passing part when the cartridge or refill package container is torn off.
Hereinafter, a work of the present invention configured as above will be described below.
In the blister package of the present invention, the case accommodation part, the content accommodation part, and the sample content accommodation part may be protrudingly molded in an arbitrary form on the transparent molding sheet, in a next process, arbitrary contents such as a salve type perfume available for long-term use are filled and accommodated in the case accommodation part, the case having the cover which may be made of metal, plastic, ceramics, or glass is stored in the case accommodation part, and the sample contents of a prototype in development for release or a not-for-sale product which completed development are filled inside the sample content accommodation part.
After filling the contents, the case, and the sample contents, the transparent or opaque covering film may be attached to the back side of the molding sheet in such a manner that openings of the case accommodation part, the content accommodation part, and the sample content accommodation part are sealed.
Next, the cartridge or refill cutting line and the sample notched line are processed on the edge part of the content accommodation part and the sample content accommodation part in order to be individually separated and torn off from a main body where the case accommodation part is located when necessary, thereby configuring the cartridge or refill package container and the sample package container.
The entire aforementioned processes are completed in a single manufacturing process in which manufacturing the cartridge or refill package container, packaging the case, and manufacturing the sample package container are provided all together through a single configuration in a single processing line.
As above, a configuration which is completely separable even with a slight external force for convenience in tearing off the cartridge or refill package container is applied to the cartridge or refill cutting line, and a plurality of notched parts for connection are on a portion of the cartridge or refill cutting line in order to prevent the cartridge or refill package container from unexpectedly separating and falling upon treatment, thereby being attached and not easily falling apart until a strong tearing force is intentionally applied.
The sample notched line is processed to have the same configuration with the notched part for connection, thereby preventing an easy separation with a weak force and enabling tearing only when a user puts a relatively strong tearing force to forcibly tear it.
Meanwhile, the projecting part for opening guidance is formed on the molding sheet 1 so that a portion of the cartridge or refill cutting line which starts to be torn off may pass. Here, the projecting part for opening guidance may maintain separation from the covering film through a space which is configured therein.
When the cartridge or refill cutting line is separated in order to tear off the cartridge or refill package container, a passing part of the projecting part for opening guidance which is positioned inside where the cartridge or refill cutting line is passed may be cut and separated together, and after separation, the cartridge or refill package container has a gap with the covering film so as to rip off the covering film. Therefore, when the contents are in use, the covering film can be promptly and simply removed so that it is possible to provide convenience in treatment.
Meanwhile, when in use, the cartridge or refill package container is cut and separated to be stored in the withdrawn case while the cover of the case is opened, and then the covering film is removed to use the contents, or the refill package container is opened and inserted into the case to use the contents.
The sample package container is used after being torn off by using the sample notched line, and then the sample contents are used after the covering film is removed.
While the embodiments of the present invention has been described, it should be understood by those skilled in the art that various alternations and changes in form may be made therein without departing from the scope of the invention as defined by the appended claims.
