Description

[Detailed description of the invention] <Industrial application field> This invention has a lip extending from the outer periphery at the upper end, and the lip is made of paper or has a tapered diameter that decreases from the bottom toward the bottom. This dispenser stores a row of polymerized laminated disposable cups made of foamed resin in a bag made of film material, and takes out the polymerized laminated cups one by one from the lower end of the bag.

<Prior Art> Such a dispenser was proposed by the present inventor in Japanese Patent Publication No. 54-16798 (Japanese Unexamined Patent Publication No. 52-123775) and is well known.

In the above-mentioned known example, the bag is made of a heat-shrinkable film material, and the part slightly above the bottom of the bag is heat-shrinked in an annular shape until it comes into close contact with just below the lip of the bottom cup. The lip is forced through the portion and the cups are taken out one by one from the bottom.

<Problems to be solved by the invention> However, heat-shrinkable film materials are much more expensive than non-heat-shrinkable film materials, and they are difficult to use until they fit tightly under the lip of the bottom cup. Even if it is heat-shrinked in an annular shape, there is a taper from the lip down, so if the width of the annular heat-shrinkable part (the length along the longitudinal direction of the bag) is too wide, the diameter of the lower end of the annular heat-shrinkable part will be too large. It becomes too small for the outer diameter of the cup, making it difficult to pass the lip through and remove the cup, and if you force the cup out, the heat shrink part will tear when some cups are removed, and the function will be lost. I will lose it.

Conversely, if there is insufficient heating to form the annular heat-shrinkable portion, the underside of the lip will not be tightened enough, and even if you try to take out one cup, two will come out.

<Means for Solving the Problems> Therefore, the dispenser of the present invention has a stretchable material with a diameter slightly smaller than the outer diameter of the lip of the cup on the lower outer periphery of the bag made of film material that accommodates the polymeric laminate of the cup. The bag is characterized in that a ring-shaped band is fitted thereinto, and the ring-shaped band is partially fixed to the bag.

<Function> It is the annular band fitted around the outer circumference of the lower end of the bag and partially fixed to the bag that absorbs the entire weight of the polymeric laminate of the cup and allows the cups to be taken out in order from the bottom. , the bag containing the polymeric laminate of the cup need not be constructed of heat-shrinkable film material.

When the bottom cup of the polymeric laminate of the cup is pulled down to take it out, the part of the annular band that is not fixed to the bag slides down along with the cup, diagonally to the polymeric laminate of the cup. Become,
The lip of the cup widens the intermediate portion between the portion of the annular band that is fixed to the bag and the portion that is not secured and slides down, and passes downward through the interior of the bag that the annular band surrounds.

<Example> In the illustrated example, 1 is a cup, 2 is a lip thereof, 3 is a bag containing a row of polymerized laminates of the cup, 4 is an annular band, and 5 is an annular band partially attached to the outer surface of the bag. Indicates adhesive tapes made of paper or plastic film, etc., and adhesive labels for fixing.

The lower end of the bag 3 is closed with a heat seal or the like to accommodate the polymerized laminate of the cup, and the upper end is squeezed to form a loop 1' and tied, or fastened with adhesive tape or the like.
It should be possible to hang it from loop 1'.
If necessary, perforations may be made on the sealed bottom edge to open the bottom of the bag. Note that the diameter of the bag is larger than the outer diameter of the lip of the cup.

The annular band 4 may be non-heat shrinkable and have a diameter slightly smaller than the outer diameter of the lip, or it may be heat shrinkable and have a diameter greater than the outer diameter of the lip.

The embodiment shown in FIGS. 1 to 4 is an embodiment using a non-heat-shrinkable annular band. In this case, the annular band 4 is placed at an appropriate position below the lip of the bottom cup of the bag 3. Fitting: In this case, fix the back side 4a of the band to the outside surface of the bag 3 with adhesive tape or adhesive label 5 at only one place, and attach the part of the bag surrounded by the band to which no tape or label is attached. Narrow down. In the case of a cup with an outer diameter of lip 2 of 77 mm and a stack pitch P of 9 mm when laminated, the annular band 4 has a folded diameter (width when the cylindrical film is flattened = 1/2 of the circumferential length of the cylinder). ) 118mm (diameter approx. 75mm),
A polyethylene tube with a thickness of 50μm and a width of about 10~
Sliced into 15mm rounds is suitable. Bag 3 is
A polyethylene tube with a folded diameter of 150 mm (approximately 95 mm in diameter) and a thickness of 10 μm was used.

Cut the bottom end of the bag 3 above the seal, hold the bottom cup No. 1, and pull it down.The lip 2 of the cup will be surrounded by the annular band 4 and will pull the inside of the bag, which is slightly squeezed, downward. As a result, the front side 4a of the annular band 4, whose rear side is fixed to the bag 3 with adhesive tape 5, etc., slips down and becomes oblique to the polymeric laminate of the cups, and the lip of the lowest cup is attached to the annular band. The lip moves downward while expanding the left and right intermediate parts 4b between the rear side that is fixed to the bag and the front side 4a that has shifted down, and both left and right sides of the lip almost pass through this left and right intermediate part 4b. Then, the rear part of the lip facing the rear of the band slips out from the rear of the band fixed with adhesive tape. Therefore, after that, you can pull it down and take out the bottom cup with almost no resistance. In this way, when you take out the bottom cup,
The stack of cups inside the bag moves downward, and the cup in the second row from the bottom is bitten into the inside surrounded by the left and right middle parts 4b of the annular band 4 on both left and right sides of the lip, and the front edge of the lip is inserted into the inside where the left and right intermediate parts 4b of the annular band 4 are surrounded. It is held in the bag 3 by being supported by the upper edge of the front side 4a which is sloping down. Of course, it can be taken out in the same way by holding the second cup from the bottom and pulling it downward, and the third cup from the bottom is held by the annular band 4. In this way, the stacked cups in the bag can be taken out one by one from the bottom.

As mentioned above, the width of the annular band is about 10 to 15 mm, but specifically, when the left and right sides of the lip pass almost below the left and right intermediate parts 4b and 4b of the oblique band, the rear part of the lip becomes a bag. Preferably, the width is determined so that the lip passes downward through the rear part of the band fixed to the lip, and the front part of the lip bites shallowly into the front part of the band that has fallen off from above.

In this embodiment, only the rear side of the annular band 4 is fixed to the bag, but the same effect can be obtained by, for example, fixing the band at two places on the back side and the front side to the bag, and sliding the left and right intermediate parts down. It will be done.

5 and 6 show the case where heat-shrinkable polyvinyl chloride or polypropylene is used for the annular band 4, and the diameter of the annular band 4 is slightly larger than the outer diameter of the lip of the cup. For example, if the outer diameter of the lip of a cup laminated and stored in the bag 3 is 80 mm and the stack pitch is 9 mm, the folded diameter of the heat-shrinkable tube that is cut into rings to obtain the annular band 4 is 148 mm (approximately 94.2 mm in diameter). , with a thickness of 30 μm. This annular band 4 is fitted into the bag 3, positioned so as to surround the lip of the bottom cup, and the back side of the annular band of the bag is fixed to the outer surface of the bag 3 with an adhesive paper label 5, and the internal temperature is
The annular band 4 is heat-shrinked by passing through a heating tunnel at 120° C. for 2 seconds.

As a result, the rear part of the annular band where the adhesive paper label 5 is pasted is blocked by the label and hardly shrinks.
Since the shrinkage occurs in the unlabeled portion, the left and right sides and front of the bag are squeezed so that it clings to the outer surface of the left and right sides and front of the lip of the cup.

Therefore, when the bottom cup is pulled down, the lip slides down the front side 4a of the contracted annular band and makes it diagonal, and the left and right sides of the lip expand the left and right intermediate parts 4b of the band slightly while pulling the inside of the bag downward. It can be moved and taken out one by one from the bottom in the same manner as in the embodiment shown in FIGS. 1 to 4 described above.

When using a non-heat-shrinkable annular band, there is no need for a heat-shrinking process, and the band can be fixed anywhere below the lip of the bottom cup, but the annular band can be fixed anywhere below the lip of the cup. Depending on the outer diameter, it is necessary to prepare various types with slightly smaller diameters.

However, if the annular band 4 is made of heat-shrinkable material and is heat-shrinked so as to surround the lip of the bottom cup, the annular band 4 should be made with a diameter slightly larger than that of the lip of the cup. Can be commonly used for various sizes of cups with small outer diameter. In this case, some heat-shrinkable tubes have the characteristic of shrinking in length mainly in the circumferential direction, and others have the characteristic of shrinking in length in both the circumferential and longitudinal directions, so the former (mainly (Shrink the circumferential length to)
When you get the circular band from the tube, bag 3
In this case, the tube should be fitted so as to surround the bottom cup and then heat-shrinked. However, when obtaining an annular band from the latter tube, the width should be widened in anticipation of vertical shrinkage of the band, and the bottom cup should be made wide. In addition to the lip, it is preferable that the bag be fitted into the bag so as to surround the lips of a plurality of cups from below, such as the lip of the cup above it, so that even if it contracts in the vertical direction, the lip of the lowest cup is securely tightened.

When using a heat-shrinkable annular band, the area where the adhesive tape or adhesive label that is fixed to the bag will hardly shrink due to heat, so the length of the tape or label in the circumferential direction should be adjusted appropriately. The downward pulling force required to take out the cup can be set appropriately.

Incidentally, when an adhesive label is used to fix one side of the annular band to the bag, information such as a company name, trademark, etc. can be displayed on this label.

<Effects of the Invention> According to the present invention, a dispenser can be provided at low cost since no heat-shrinkable film material is used in the bag that accommodates the polymeric laminate of the cup. The bag is squeezed by the annular band only slightly more than the outside diameter of the lip of the cup, and when the bag is pulled down to take out the cup, the annular band becomes oblique to the stack of cups, and the bag is squeezed in the middle between the left and right sides of the band. Only the force required to expand the parts can be taken out, making removal extremely easy.
