Description

  The present invention relates to a container for confectionery sales by a beverage vending machine.

  In recent years, vending machines have become widespread and the products handled include a wide range of products, including liquid drinks such as soft drinks and alcoholic beverages, foods such as confectionery and dietary supplements, and non-food products such as masks and stockings. Has crossed.

  Traditionally, a confectionery vending machine is often provided separately with a beverage vending machine, which is extremely inconvenient from the viewpoint of a user who wants to purchase at the same time. In addition, the distribution cost is extremely uneconomical. In view of such a situation, by filling confectionery into a plastic container having substantially the same shape as a can container provided in a beverage vending machine, without providing a confectionery vending machine, It has been proposed to provide confectionery (Patent Documents 1 and 2). Moreover, it is a container of the shape substantially the same as the can container provided with the vending machine for drinks, Comprising: The thing made from paper blanks is also known (patent document 3).

Japanese Patent Laid-Open No. 7-165226 Japanese Utility Model Publication No. 3-15321 Japanese Utility Model Publication No. 5-86818

  However, the containers of Patent Documents 1 and 2 have a problem that the raw materials are high because they are made of plastic and are difficult to be effectively used as recycled materials.

  On the other hand, since the container described in Patent Document 3 is made from a paper blank, its raw material is inexpensive and easy to recycle. However, a container made from a paper blank has a large coefficient of friction, and therefore, it may not be able to be smoothly guided to the take-out port at the time of sale. In addition, containers made from paper blanks are vulnerable to moisture, so the containers themselves are weakened by moisture generated during cold storage in vending machines, and this weakening further increases the coefficient of friction and makes it difficult to remove them. There was a problem of making it.

  Therefore, the present invention has been made to solve such problems of the prior art, and is a confectionery container suitable for beverage vending machines, which can be manufactured at low cost and can be easily recycled. It is another object of the present invention to provide a container that can be smoothly guided to the outlet of a vending machine regardless of the presence or absence of moisture.

That is, the invention according to claim 1 is a packaging container for a vending machine, which is composed of paper as a main constituent material, a container storing confectionery, and a shrink film covering the cylindrical body of the container. There,
Both of the static friction coefficient and the dynamic friction coefficient of the shrink film are 0.4 or less.

  According to the present invention, the container containing the confectionery is made of paper as a main constituent material, and its production is inexpensive and easy to recycle, but the cylindrical body of the container is covered with the shrink film. Since both the coefficient of static friction and the coefficient of dynamic friction of the shrink film thus exposed on the outer surface of the container are 0.4 or less, it is smoothly retained without being caught inside the vending machine at the time of sale. It can be guided to the outlet. Moreover, since the container is covered with the shrink film, it does not weaken due to contact with moisture generated during cold storage, and therefore can be smoothly guided to the outlet of the vending machine regardless of the presence or absence of moisture. It becomes possible.

  The shrink film only needs to be tightly attached to the entire cylindrical barrel portion of the container, for example, using a uniaxially stretched film having a length protruding above and below the container, and its stretching direction. The tubular body can be covered by shrinking the shrink film after wrapping the container so that it faces the circumferential direction of the container and bonding both ends together. Also, using a biaxially stretched film as the shrink film, the entire container including both ends of the container is wrapped with the shrink film, and the shrink film is contracted, so that the entire container including the both ends and the cylindrical body is wrapped. It may be coated.

  Next, invention of Claim 2 specifies the material of the said shrink film. That is, the invention according to claim 2 is the packaging container for vending machines according to claim 1, wherein the shrink film is made of a stretched polystyrene film. And according to this invention, in addition to being able to guide to the taking-out port of the vending machine smoothly regardless of the presence or absence of moisture, the shrink film also deteriorates when cooled inside the vending machine. There will be no cracks or easy tears. For this reason, it becomes possible to store stably for a long time in a vending machine. In addition, since the shrink film is not damaged even after being stored for a long time, it can be smoothly guided to the take-out port even after being stored for a long time.

  According to a third aspect of the present invention, the shrink film has a multilayer structure, and the shrink performance and the slip performance are each borne by another layer. That is, the invention according to claim 3 is characterized in that the shrink film is composed of a base film and a surface layer that reduces the static friction coefficient and the dynamic friction coefficient. Packaging container. As the substrate film, in addition to the stretched polystyrene film, a stretched polyethylene film, a stretched polypropylene film, a stretched polyvinyl chloride film, and the like can be used. Moreover, as the surface layer for reducing the static friction coefficient and the dynamic friction coefficient, a coating film of a paint obtained by adding a lubricant to a thermoplastic resin can be used. Examples of the thermoplastic resin include polyvinyl chloride, polyvinyl acetate, cellulose resin, acrylic resin, and urethane resin. Further, as the lubricant, a surfactant, various waxes, silicone oil and the like can be used.

  Next, as the cylindrical container according to the present invention, any container can be used as long as it is made of paper as a main constituent material, but the container is prevented from being damaged when dropped into the outlet of the vending machine, and In order to prevent crushing of the confectionery due to the impact at the time of dropping, it is preferable to have a high strength and have a shock absorbing property.

  The inventions described in claims 4 to 6 specify the container from such a viewpoint.

That is, in the invention according to claim 4, the container is detachably fitted to a cylindrical paper tube having openings at both ends and a peripheral wall portion of one of the openings of the paper tube.

  According to this invention, since the trunk | drum is comprised from the cylindrical paper tube, it can manufacture cheaply and it is easy to recycle as a paper raw material after disposal. Moreover, since the cylindrical paper tube is superior in cushioning properties compared to a plastic container, for example, when it is dropped into the take-out port of a vending machine, the confectionery collides with the inner wall of the container. It is possible to prevent the confectionery from being crushed by absorbing the impact of the confectionery.

  In addition, as the first sealing member and the second sealing member that are fitted into the openings at both ends of the cylindrical paper tube, a paper sealing member, a composite formed by laminating paper and plastic A sealing member made of a material or a plastic sealing member can be used.

  When paper sealing members are used as the first sealing member and the second sealing member, these sealing members are also inexpensive and easy to recycle, and the confectionery that collides with the inner surfaces of these sealing members is used. Crushing can also be prevented. In addition, since the opening part of the both ends of a cylindrical paper tube is fitted by these 1st sealing members and the 2nd sealing member, the protection performance of the accommodated confectionery is also excellent. For example, protection performance such as water resistance, heat resistance, scratch resistance, and antifouling properties.

  In addition, when a composite material of paper and plastic is used as the first sealing member and the second sealing member, since the composite material uses paper, these sealing members are also inexpensive and easy to recycle. Moreover, crushing of confectionery that collides with the inner surface of the sealing member can be prevented. Further, since these sealing members use plastic in addition to paper, the protection performance is remarkably improved as compared with the case where the sealing member is composed of a single paper.

  Next, when a plastic sealing member is used as the first sealing member and the second sealing member, the case where the sealing member is composed of a single paper or a composite material of paper and plastic. The protection performance is further improved as compared with the case where it is configured.

  Next, the invention according to claim 5 is the packaging container for vending machines according to claim 4, wherein the second sealing member is stuck to the paper tube. According to this invention, while the first sealing member is detachably fitted, the second sealing member is stuck to the paper tube and is difficult to attach and detach. This is always done by removing the first sealing member. For this reason, both ends are not opened by mistake, and it becomes possible to prevent the confectionery from falling.

  The invention according to claim 6 is characterized in that the paper tube is a spiral paper tube having a thickness of 0.1 to 5.0 mm, and the maximum inner diameter of the paper tube is in a range of 50 to 300 mm. The packaging container for a vending machine according to claim 4 or 5. According to this invention, since the paper tube is a spiral paper tube, it is easy to manufacture at low cost. Moreover, since it is a spiral paper tube having a thickness of 0.1 mm or more, the strength is high, and, for example, it is not distorted when dropped into the take-out port of a vending machine, and confectionery can be prevented from being crushed. On the other hand, if it is thicker than 5 mm, the manufacturing cost becomes high. Since the maximum inner diameter of the paper tube is in the range of 50 to 300 mm, it can be sold in the same manner as a beverage can with a general-purpose beverage vending machine.

  The invention according to claim 7 is the packaging container for vending machines according to any one of claims 4 to 6, wherein an opening cut line is formed on the first sealing member. It is. According to this invention, the first sealing member can be cut from the score line and easily opened.

It is a packaging container for vending machines in any one of Claims 4-7 characterized by the above-mentioned. In this invention, since the cylindrical member of the sealing member is manufactured by sacking, the manufacturing becomes easy. In addition, as a cover member, the flat board member of the substantially same shape as the opening edge part of this cylindrical member can be used, and it can fix by winding the periphery at the edge part of a cylindrical member.

  As described above, according to the present invention, there is an effect that it is inexpensive and easy to recycle, and can be smoothly guided to the outlet of the vending machine regardless of the presence or absence of moisture.

The perspective view which isolate | separates and shows the container which concerns on the Example of this invention into a paper tube, a 1st sealing member, and a 2nd sealing member. The perspective view of the Example of this invention The perspective view of the 2nd example of the present invention. The perspective view of the 3rd example of the present invention. The perspective view of the 4th example of the present invention.

  Next, the present invention will be described with reference to the drawings.

  The packaging container according to the present invention includes paper as a main constituent material, a container containing confectionery, and a shrink film covering the cylindrical body of the container.

  Any container may be used, but, for example, a cylindrical paper tube, a bottomed cylindrical first sealing member, and a bottomed cylindrical second sealing member may constitute a main part thereof. It can be preferably used. FIG. 1 shows the container separated into a paper tube, a first sealing member, and a second sealing member. FIG. 2 shows a packaging container obtained by covering the entire assembled container with a shrink film.

  In this example, the first sealing member is detachably fitted to one of the opening peripheral walls of the openings at both ends of the cylindrical paper tube. In the example shown in the figure, an opening cut line is provided on the peripheral wall of the first sealing member. In this case, the first sealing member can be opened by cutting the peripheral wall of the first sealing member from the cut line when opening. In this case, it is preferable that the first sealing member has its tip end portion remaining on the cylindrical paper tube after being cut and fixed to the cylindrical paper tube. Even in this case, the cut first sealing member can be separated from the cylindrical paper tube and can be put on the end of the cylindrical paper tube again. That is, it is detachable.

  Next, the second sealing member is fitted to the other opening peripheral wall portion. The second sealing member may be adhered and fixed to the cylindrical paper tube, or may be detachably fitted to the cylindrical paper tube. Preferably, the second sealing member is stuck and fixed to the cylindrical paper tube. In this case, the container is always opened by removing the first sealing member. For this reason, both ends are not opened by mistake, and it becomes possible to prevent the confectionery from falling.

  In addition, as shown in FIG. 1, it is desirable that the length a of the cylindrical paper tube is greater than or equal to the sum b + c of the height b of the first sealing member and the height c of the second sealing member. . The example shown in FIGS. 1 and 2 satisfies a = b + c. Therefore, in the perspective view of FIG. 2, the cylindrical paper tube is hidden inside the first sealing member and the second sealing member.

And the packaging container for vending machines of this invention coat | covers the whole container containing the cylindrical trunk | drum or cylindrical trunk | drum of this container with a shrink film (refer FIG. 2). In this example, the entire container including both ends is wrapped with a shrink film, and the shrink film is contracted to cover the entire container including the both ends and the cylindrical body. In either case of covering the entire container or selectively covering the cylindrical body, the shrink film is a static friction against metal measured in accordance with JIS K 7125 after shrinking. Both the coefficient and the dynamic friction coefficient need to be 0.4 or less. If the coefficient of static friction and the coefficient of dynamic friction are larger than this, when selling with a vending machine, the product may be caught inside and not smoothly guided to the product outlet. In general, since the dynamic friction coefficient is smaller than the static friction coefficient, if the static friction coefficient for a metal measured according to JIS K 7125 is 0.4 or less, the dynamic friction coefficient may be estimated to be 0.4 or less. it can.

  Next, since the packaging container for a vending machine uses a cylindrical paper tube for the body part of the container, it can be manufactured at a low cost and can be easily recycled as a paper material after disposal. Moreover, since the cylindrical paper tube is superior in cushioning properties compared to a plastic container, for example, when it is dropped into the take-out port of a vending machine, the confectionery collides with the inner wall of the container. It is possible to prevent the confectionery from being crushed by absorbing the impact of the confectionery. In addition, since the opening part of the both ends of a cylindrical paper tube is fitted by these 1st sealing members and the 2nd sealing member, the protection performance of the accommodated confectionery is also excellent. For example, protection performance such as water resistance, heat resistance, scratch resistance, and antifouling properties.

  Next, each member which comprises the packaging container of this invention is demonstrated.

  First, for a cylindrical paper tube, the outer shape of the packaging container for a vending machine of the present invention is determined by this cylindrical container. For this reason, the cylindrical paper tube needs to have an outer shape and a size suitable for a general-purpose beverage vending machine. That is, the outer diameter of the cylindrical paper tube needs to be in the range of about 50 to 310 mm. As will be described later, since the thickness of the paper tube is 0.1 to 5 mm, the maximum inner diameter is 50 to 300 mm.

  A spiral paper tube is desirable as the cylindrical paper tube. Spiral paper tubes are easy to manufacture and their manufacturing costs are low. In order to ensure high strength, it is desirable that the thickness is a spiral paper tube having a thickness of 0.1 mm or more. In the case of a spiral paper tube having a thickness of 0.1 mm or more, for example, when sold in a vending machine, it is not distorted when it is dropped into its takeout port, and confectionery can be prevented from being crushed. It may be 5 mm or less. Thicker spiral paper tubes are expensive to manufacture.

  As the cylindrical paper tube, FIG. 1 shows a cylindrical spiral paper tube, but in addition to this, various shapes such as a polygonal cylindrical shape, a cup shape, a conical shape, and an oval shape in which a central portion swells are used. Also good. FIG. 3 shows an example using a square tube-shaped paper tube having a square cross section, and FIG. 4 shows an example using an oval-shaped paper tube having a bulged central portion.

  Next, each of the first sealing member and the second sealing member has a bottomed cylindrical shape, and covers the cylindrical member constituting the peripheral wall and one of the openings of the cylindrical member. And a lid member fixed to the cylindrical member.

The cylindrical member preferably has an inner diameter that is substantially the same as the outer diameter of the cylindrical paper tube, and can be covered on the paper tube without a gap. Although a spiral paper tube can be used as such a cylindrical member, it is convenient to use a cylindrical member obtained by sacking. That is, it is possible to obtain a tubular member by rounding or bending a flat piece of paper into a tubular shape and bonding both ends thereof together. FIG. 1 is an example in which cylindrical members obtained by rounding into a cylindrical shape are used as the first sealing member and the second sealing member. Similarly, FIG. 3 uses a cylindrical member obtained by bending into a rectangular tube shape, and FIG. 4 uses a cylindrical member obtained by rounding into a truncated cone shape. Also,
When a flat piece of paper is folded, it is also possible to previously provide a pressed ruled line at the folding position and bend it according to the pressed ruled line. FIG. 5 shows an example of using a cylindrical member provided with a large number of creased lines and bent according to the creased lines. The tubular member has a polygonal cross section. In any case, the opening member can be provided on the tubular member.

  Next, as the lid member, a flat plate member having substantially the same shape as the opening end portion of the cylindrical member can be used, and the periphery thereof can be fixed by being tightened by the end portion of the cylindrical member.

  These cylindrical members and lid members can be made of a single paper, a composite material of paper and plastic, or plastic. When configured from a single piece of paper, it is inexpensive and easy to recycle, and since this single piece of paper is excellent in cushioning properties, for example, when it is dropped into the take-out port of a vending machine, confectionery is also accompanied by this fall. It is possible to prevent the confectionery from being crushed by absorbing the impact when the food collides with the inner surface of the cylindrical member or the inner surface of the lid member.

  Further, when it is composed of a composite material of paper and plastic, it is inexpensive and easy to recycle, and can be prevented from crushing confectionery even when dropped into the take-out port of the vending machine. In addition, the protection performance such as water resistance, heat resistance, scratch resistance, and antifouling property is remarkably improved as compared with the case where the paper is composed of a single paper. Polyethylene or polyester can be used as the plastic. For example, it is a laminate in which polyethylene or polyester is laminated on one side or both sides of paper. Further, it is also possible to use a laminate in which polyethylene is laminated on one side and polyester is laminated on the other side around paper.

  Further, when the cylindrical member and the lid member are made of plastic, the protection performance is further improved as compared with a case where the cylindrical member and the lid member are made of paper alone or a composite material of paper and plastic. Polyethylene or polyester can be used as the plastic.

  Next, this container first fits one of the first sealing member and the second sealing member to the end of the cylindrical paper tube to seal one end of the cylindrical paper tube, After the confectionery is stored inside the cylindrical paper tube, the other sealing member can be fitted into the opening end of the cylindrical paper tube.

  Next, as the shrink film according to the present invention, a uniaxially stretched film or a biaxially stretched film can be used. When selectively covering the cylindrical body of the container, it is desirable to use a uniaxially stretched film, and the shrinking direction is wrapped so as to coincide with the circumferential direction of the cylindrical body, and it is shrunk by heating. By this, it adheres to a cylindrical trunk | drum and this is bound. At this time, even when the shrink film is wrapped so as to protrude in the vertical direction of the cylindrical body portion, the protruding portion contracts and closely contacts the upper and lower lid members of the container. In addition, as in the illustrated example, when the entire container including the cylindrical body and both ends is covered with a shrink film, it is desirable to use a biaxially stretched film.

  As such a shrink film, a stretched polystyrene film can be used as described above. In addition, it is also possible to use a stretched polyethylene terephthalate film. In any case, both the static friction coefficient and the dynamic friction coefficient after shrinkage must be 0.4 or less.

In addition, the shrink film can have a multi-layer structure, and each of the necessary functions can be borne by separate layers. That is, the shrink film is a shrink film in which the shrink function is imposed on the base film, and a paint containing a lubricant is applied to the base film, and the static friction coefficient and the dynamic friction coefficient are 0.4 or less by this coating film. As the lubricant, surfactants, various waxes, silicone oils and the like can be used, and these lubricants may be mixed with a solvent together with a thermoplastic resin and applied to a base film. As the base film, in addition to the above-mentioned stretched polystyrene film, stretched polyethylene film, stretched polypropylene film, stretched polyvinyl chloride film and the like can be used. As the thermoplastic resin, polyvinyl chloride, polyvinyl acetate, cellulose resin, acrylic resin, etc. Resin, urethane resin, etc. can be used.
