Description

[Detailed Description of the Invention] The present invention relates to a thermoplastic synthetic resin bag that can be used not only as a packaging bag for disposable cups but also as a cup dispenser.

Disposable pots (for example, paper pots, etc.) are sold in relatively high units, such as 30 to 100 pieces.

At this time, to prevent the disposable cups from getting dirty or falling apart, they were usually packed together in transparent plastic bags and sold as is.

Therefore, consumers had to take the disposable cups they had purchased out of the plastic bags and repack them into special cup dispensers.

A cup dispenser is a metal or plastic device that allows a predetermined number of disposable cups to be taken out one by one by grasping the bottom of the disposable cups and pulling them downward.

However, cup dispensers are generally relatively expensive, and in order to install them, they must be fixed to a suitable wall surface, and in the sense that they require a fixed place, it is necessary to fix a set of cup dispensers. Once stored, the installation location cannot be easily changed, and as a result, the places where it can be used are limited, so it cannot necessarily be called a convenient and convenient device.

Therefore, even if you want to use a large amount of disposable cups in general households, prefabricated lodgings at construction sites that are only used for a short period of time, election offices, etc., you have to purchase cup dispensers as well. There was a tendency to only purchase disposable chips in small units of about 10 pieces.

Therefore, the purpose of the present invention is to function as a packaging bag for disposable cups when they are sold, and to function as a cup dispenser when consumers use the disposable cups inside the bag. It is an object of the present invention to provide a thermoplastic synthetic resin bag body configured as described above.

In short, the bag body of the present invention is open at one end and welded at the other end, supporting the enlarged size end of the disposable tip contained in the bag and the reduced size end. The bag has a notch in the welded end portion defining a tip outlet, which is formed so that only one tip can be removed from the bag by pulling it out.

Hereinafter, the content of the present invention will be explained in more detail with reference to the drawings.

However, the illustrated device and the device described below are merely examples of the present invention, and the scope of the present invention should be construed to be limited to only what is illustrated and specifically described. isn't it.

FIG. 1 is a plan view showing an example of a bag 1 according to the present invention.

The upper end 2 of the bag 1 is an open end, from which disposable cups can be taken in and out at any time.

The lower end of the bag body 1 is a welded end 3 that is welded into a band shape.

The welded end 3 is provided with a notch 4 that defines a tip outlet.

The cutout 4 is, for example, contoured by a perforation 5 .

Therefore, as shown in FIG. 2, the tip outlet 6 can be opened by pinching the notch 4 surrounded by the perforations with fingers and tearing it off.

The size of the notch 4, that is, the size of the tip outlet 6, is
As is clear from FIG. 2, by supporting the enlarged size end 8 of the disposable tip 7 shown by the dashed line and pulling out the reduced size end 9, only one tip is detached from the bag body 1. It must be of such a size that it can be used.

Specifically, the type and size of the tip loaded in the bag,
The size of the notch can be appropriately determined by considering the quantity and the like.

FIG. 3 shows another embodiment of the invention.

At the lower end of the bag 1a, there is a planar welded end 3a in the shape of a right triangle.

A notch 4a is formed by two parallel perforations 5a perpendicular to the slope forming the welded end 3a and a perforation 5a on the slope connecting these two parallel perforations.
is contoured.

FIG. 4 illustrates yet another embodiment of the invention.

In this embodiment, a crown-shaped welded end 3b is formed at the lower end of the bag body 1b.

Similarly, a notch 4b, which is contoured by a perforation line 5b, is arranged in said welded end 3b.

FIG. 5 illustrates yet another embodiment of the invention.

In this embodiment, the welded end 3C provided at the lower end of the bag 1C
is formed not in a planar shape but in a linear shape.

Further, the cut portion 4C can be configured by forming the perforation line 5C into a semicircular shape.

When the welded end is formed into a planar shape as shown in Figures 1, 2, and 3, when the bag of the present invention is used as a cup dispenser, the tensile stress applied to the cup outlet when the cup is pulled out is reduced. On the other hand, it is possible to effectively prevent cracks from forming at the tip outlet.

Furthermore, as shown in Figure 3, if the opening direction of the tip outlet is arranged in an inclined direction rather than perpendicular to the bag, even if a large amount of tips are loaded into the bag, the disposable tips will not be removed. The tip is effectively locked at the tip outlet, and even if the film at the upper end of the tip is cracked, the risk of the inner tip falling out of the bag all at once is reduced.

Furthermore, if the welded end is formed into a crown-like planar shape as shown in FIG. 4, cracking of the film due to the tensile stress applied to the tip outlet when the tip is pulled out can be more effectively prevented.

That is, it means that the effect of reinforcing the tip outlet is even higher.

On the other hand, the disposable tip that is loaded into the bag is not heavy like a paper tip, but is lightweight and made of a thermoplastic synthetic resin sheet such as polypropylene or polystyrene using vacuum forming or pressure forming. In the case of a plastic disposable tip, the welded end does not need to be formed into a planar shape.
It may be formed linearly as shown in the figure.

In this case, in order to disperse the tensile stress when pulling out the tip from the bag, it is preferable to form the tip outlet with a semicircular perforation line as shown in FIG. 5.

The material constituting the bag of the present invention is, for example, a film or sheet of thermoplastic synthetic resin such as polyethylene, polyethylene terephthalate, polypropylene, polybutadiene, etc.

Therefore, the bag itself of the present invention can be formed by, for example, a conventional inflation method.

Further, the thickness of the thermoplastic synthetic resin film used in the bag according to the present invention itself is not an absolute requirement of the present invention.

Generally, thicknesses within the range of 20μ to 200μ can be used as appropriate.

Specifically, the type of film used, the mechanical properties of the film used (i.e., flexibility, strength, etc.), the type of disposable tip to be loaded (e.g., paper tip or plastic tip), and the type of disposable tip to be loaded (e.g., paper tip or plastic tip), The most appropriate film thickness may be selected by comprehensively considering various factors such as the loading amount and the form of the welded end (ie, planar or linear).

Welding of one end of the bag body, whether surface welding or linear welding, can be easily carried out by using a conventional sealing device, such as an electric heat sealer or an ultrasonic welding machine.

Furthermore, perforations for forming the contour of the notch can be easily placed in the bag by using a commonly used perforation cutting device.

Once a predetermined number of disposable tips are loaded into the bag according to the present invention, the open end is tied up with tape or string, the bag is sealed, and it is sold in that state.

When a consumer purchases this and uses it, the tape or string used to form the densely sealed area is driven into the wall at an appropriate height, and the travel gear is hung by hanging it on a nail or banger hook. Lower.

Thereafter, a notch provided at the welded end of the lower end of the bag is cut out along the perforation line to open a tip outlet.

As explained above, when disposable chips are sold in relatively high units such as 50 to 100, they are generally sold by being packaged in thermoplastic film bags, but in this invention, One end of the bag used for this packaging supports the enlarged size end of the disposable tip to be bottled in the bag, and the disposable tip is inserted one by one by pulling out the reduced size end. A welded end is provided with a notch defining a tip opening for removal from the bag.

In this way, in the past, even if disposable cups were purchased for each high unit quantity, effective consumption of cups could not be achieved unless a special cup dispenser was used, but according to the present invention, disposable cups for packaging Since the bag body itself also functions as a cup dispenser, there is no need for a separate dedicated cup dispenser, and disposable cups can be taken out one by one at any location, making it an inexpensive and functional disposable cup. can be consumed.
