Description

  The present invention relates to a one-time paper cup used mainly for drinking and drinking in vending machines, rest areas, outdoor places, etc. In particular, the spoon is separably attached to one side of the outer peripheral surface of the paper cup. For a one-time paper cup.

  In general, paper cups used for drinking tea with coffee and other drinking water are easy to carry and post-process, and are mainly used in vending machines, rest areas and outdoor areas. Used for reuse.

  However, when using a paper cup as described above, in order to properly mix the contents filled in the cup, the contents must be thoroughly stirred using a spoon or the like. In the vending machine, there is no separate spoon and it is difficult to mix the contents inside the cup, and a separate spoon is prepared for drinking coffee (coffee mixer) etc. once in a general office or outdoor area. If not, most people will fold up the coffee mixer paper bag and use it as a spoon substitute, of course, even if a spoon is prepared, multiple people will share one spoon. There was a drawback that it was not hygienic and clean.

  Therefore, recently, in order to maintain easy mixing of contents by using a paper cup and hygienic cleanliness by using a spoon, a spoon is attached to the outer peripheral surface of the paper cup so that it can be separated. Spoon-attached one-time paper cups have been known.

  That is, according to Patent Document 1, as shown in FIG. 1, a paper cup to which a conventional paper spoon is attached includes an auxiliary paper 2 attached so as to wrap the outer peripheral surface of the paper cup 1, and the auxiliary paper 2. It is configured to include a paper spoon 4 that is partitioned by a cutting line on the inner surface and in which a Y-shaped folding line 5 is formed in the length direction.

  Further, according to Patent Document 2, as shown in FIG. 2, a spoon 20 having an arbitrary shape is integrated with the outer end portion 11 located on the outer side when both ends are thermally bonded when the paper cup 10 is manufactured. However, the spoon 20 is configured to be separable by the outer end portion 11 and the connecting end 21 of the paper cup 10, and a single paper cup integrally formed with the spoon is disclosed.

  According to the conventional spoon-attached one-time paper cups as described above, a large number of paper cups are stacked and transported and stored by heat-bonding or fixing the spoon in close contact with the outer peripheral surface of the paper cup by connecting ends. In the case of the one-time paper cup shown in FIG. 1, a spoon-shaped cutting line is defined on a separate auxiliary paper 2 at the production stage, and this is thermally bonded to the outer peripheral surface of the paper cup 1 As a result of this, the process of dividing the cutting line separately on the auxiliary paper 2 and the process of attaching the cutting line to the outer peripheral surface of the cup again are added, so that the manufacturing process becomes complicated. There is a problem that the spoon 4 that is divided by the cutting line on the auxiliary paper 2 is not easily separated.

  Similarly, in the case of the conventional one-time paper cup as shown in FIG. 2, the spoon 20 must be integrally attached to the outer end portion 11 of the paper cup 10 from the production stage. In addition to the complicated manufacturing process, there was a problem that the manufacturing unit cost increased.

On the other hand, in the case of the spoon attached to the outer peripheral surface of the conventional one-time paper cup as described above, the contents filled in the cup are mixed because the spoon is made of the same material as the paper cup. Therefore, when this is used, the spoon will absorb moisture in the contents, so that the support rigidity of the spoon will be lowered and the spoon will be flexible, of course, this will not allow the spoon to perform its function There were many problems such as.

  The present invention has been devised in order to improve the various problems of the prior art. The purpose of the present invention is to provide a single-use cup in which a spoon is detachably attached to one side of the outer peripheral surface of a paper cup. The front end is fixed by sandwiching the inner edge of the paper cup at the upper end, and the rear end is thermally bonded to the lower end of the paper cup so that the spoon is separably attached to the outer side of the paper cup. Of course, it is possible to reduce the production cost by simplifying the production process for attaching the spoon to the paper cup by attaching only one end of the spoon to the paper cup and attaching it to the paper cup in a separable manner. Another object of the present invention is to provide a one-time paper cup to which a spoon is attached so that the spoon can be easily separated from the paper cup.

  In addition, another object of the present invention is to fill the inside of the cup when using a spoon by coating with a synthetic resin such as vinyl over the entire spoon attached to the outer peripheral surface of the paper cup as described above. It is intended to prevent the spoon from losing its rigidity and becoming flexible by absorbing the moisture of the prepared contents.

As a technical means for achieving the above object, the present invention is to wind a fan-shaped main body around a cylinder, join the vertically overlapped portions, and provide a bottom plate at the lower end for sealing. The upper end of the lever is attached to a spoon that includes a paper cup having an edge that is curled and wound outward so that drinking water can be drunk, and a spoon that is separably attached to the outer peripheral surface of the paper cup. In a pattern paper cup;
The tip of the spoon is sandwiched inside the edge of the outer periphery of the paper cup, and the back end of the spoon is provided with a heat-bonding part and is thermally bonded to the outer periphery of the lower side of the paper cup. By preparing a paper cup once with a spoon attached to it.

  The spoon is coated through a synthetic resin over the entire outer periphery of the remaining portion excluding the thermal bonding portion at the rear end.

  On the other hand, as a means of another embodiment of the present invention, a fan-shaped main body is wound with a cylinder, and its vertically overlapped portion is joined, and a bottom plate is provided at its lower end so as to be sealed. In a spoon-attached paper cup configured to include a paper cup having an edge curled and wound outward so that drinking water can be drunk, and a spoon that is separably attached to the outer peripheral surface of the paper cup, The spoon is characterized in that the rear end is bonded to the surface of the paper cup, and the front end is fixed with the front end sandwiched between the vertical overlapping portions.

  At this time, the tip of the spoon is sandwiched between the vertical overlapping portions, but does not exceed 1/2 with respect to the overlapping width of the vertical overlapping portions.

  As described above, according to the one-time paper cup to which the spoon of the present invention is attached, after the tip of the spoon is sandwiched in the edge of the paper cup, only the rear end of the spoon is thermally bonded to the paper cup. The ability to attach the spoon in a separable manner simplifies the production process for attaching the spoon to the paper cup, thus reducing the production cost, and of course has the advantage that it is easy to separate the spoon from the paper cup. .

  In addition, according to the configuration of another embodiment, the tip is immediately separated by the elasticity itself at the moment when the tip is separated by the vertical overlapping portion, but there is an advantage that it is easy to grasp the tip and remove the rear end.

  In addition, by coating the entire surface of the spoon through a synthetic resin material such as vinyl, the spoon will absorb moisture from the contents filled inside the cup and lose its rigidity and become flexible. There is an effect that can be prevented.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 3 is a perspective view illustrating a one-time paper cup with a spoon attached thereto according to a preferred embodiment of the present invention, and FIG. 4 is a cross-sectional view illustrating a cross section taken along line AA of FIG.

  As shown in the figure, the one-time paper cup to which the spoon according to the present invention is attached is formed by winding a fan-shaped main body 101 in a cylinder and joining the vertical overlapping portion 120 to the bottom plate (not shown). A paper cup 100 having an edge 110 that is curled and wound outwardly so that drinking water can be drunk.

  Further, the front end 201 of the spoon 200 provided for mixing the contents filled in the paper cup 100 is sandwiched inside the edge 110 formed at the upper end of the paper cup 100 as described above, and the rear end of the spoon 200 A thermal bonding portion 210 is formed on 202 and is thermally bonded to the outer peripheral surface of the lower side of the paper cup 100 through high frequency or ultrasonic processing, and is separably attached to the paper cup.

  Here, as shown in FIG. 7, the spoon 200 is provided with a “Y” -shaped fold line 220 from the lower end central portion to the upper end, and the thermal bonding portion 210 is provided on one outer peripheral surface. The removed portion is coated with a synthetic resin 230 such as vinyl.

  Accordingly, the following is a close look at the operation and effect of the present invention formed with the above-described configuration.

  Referring to FIGS. 3 to 4, the single paper cup with the spoon attached according to the present invention is provided at the upper end of the paper cup 100 so that the user can drink easily. The front end 201 of the spoon 200 is sandwiched inside the edge portion 110, and the rear end 202 of the spoon 200 is thermally bonded to the lower outer peripheral surface of the paper cup 100 so as to be separable, whereby the spoon 200 is attached to the paper cup 200. In the process of adhering, the tip 201 of the spoon 200 is locked and fixed by the process of being easily inserted into the edge 110 of the paper cup 100, and only the rear end 202 can be fixed by thermal bonding. Not only can the production process be reduced, but also the production unit cost can be reduced.

  In addition, as described above, the spoon can be removed by inserting the tip 201 of the spoon 200 inside the edge 110 and thermally bonding only the rear end 202 to the outer peripheral surface of the paper cup 100 through thermal bonding. This means that it can be firmly fixed to the outer peripheral surface of the cup, and this makes it easy to stack, store, transport and handle the paper cup even when the spoon is attached.

  5 and 6 show another embodiment of the present invention.

  The characteristic structure here is that the paper cup 100 is wrapped around a fan-shaped main body 101 in the same manner as in the previous case, the vertical overlapping portion 120 is joined, and the lower end is provided with a bottom plate and sealed. Thus, at the upper end, a paper cup 100 having a curled edge portion 110 wound outward so that drinking water can be drunk, and a spoon 200 detachably attached to the outer peripheral surface of the paper cup 100 are included. The spoon 200 is characterized in that a rear end 202 is adhered to the surface of the paper cup 100 and the front end 201 is sandwiched and fixed between the vertical overlapping portions 120.

  At this time, the tip 201 is preferably set so that it does not exceed 1/2 with respect to the overlap width W, more preferably about 1/2 to 1/4. It is sufficient that it does not come off easily within the range, and it is just enough.

  The paper cup manufacturing method configured as in the present embodiment is almost the same as the previous case, and after simply attaching the spoon 200 to the surface of the fan-shaped main body 101 in advance, the main body is wound in a cylindrical shape and manufactured integrally. That is.

  That is, as shown in FIG. 3, the rear end 202 of the spoon 200 is temporarily bonded with a general adhesive at a position that allows the tip 201 of the spoon 200 to reach the vertical overlapping portion 120. When the 101 is wound into a cylindrical shape with a jig (not shown), the vertical overlapping portion 120 is heat-bonded so that the end of the direction in which the spoon is attached goes inward.

  Then, in the next step, the circular bottom plate is thermally bonded along the lower end of the main body 101, and the curling edge 110 is formed at the upper end.

  When the tip 201 of the spoon 200 attached to the middle stage of the main body 101 is removed from the vertical overlapping portion, the tip 201 comes to float from the cylindrical surface due to the elasticity of the spoon 200 itself.

  Therefore, it is possible to separate the spoon 200 very easily by grasping that portion and taking the bonded portion of the rear end 202.

  On the other hand, in the case where the spoon fixed as described above is separated from the paper cup by using a paper cup, the user holds the center portion of the spoon 200 with the hand and holds it to the outside of the paper cup 100. If this happens, the tip 201 of the spoon 200 sandwiched between the edges 110 while the center of the spoon 200 is bent at a predetermined angle can easily come out of the edges 110, and the rear end 202 of the spoon 200 However, the portion that is thermally bonded to the paper cup 100 is separated by the attractive force as described above, and the spoon can be easily separated from the paper cup.

  Subsequently, the spoon 200 separated from the paper cup 100 as described above is provided with a “Y” -shaped fold line 220 from the center of the lower end to the upper end as shown in FIG. 3 or FIG. When the spoon 200 is used by folding the spoon along the fold line 220, it will have a small spoon shape. When mixing things, the spoon bends and the contents in the paper cup are not properly mixed.

  In addition, a synthetic resin material 230 such as vinyl is applied to the entire outer surface of one side of the spoon 200 as described above over the entire remaining portion excluding the thermal bonding portion 210 formed at the rear end 202 of the spoon 200 described above. When the spoon is used, the spoon absorbs moisture from the contents filled in the cup and loses its rigidity to prevent it from becoming flexible.

  Here, the reason why the coating process is not performed only on the thermal bonding part 210 of the spoon 200 is that the synthetic resin coated when the spoon 200 is bonded to the paper cup 100 using high frequency or ultrasonic waves is used. This is to prevent the poor adhesion of the spoon by sticking.

  INDUSTRIAL APPLICABILITY The present invention can be applied to a one-time paper cup used mainly for drinking beverages and the like in vending machines, rest areas, and outdoors.
