Description

  The present invention relates to a cup sleeve and a cup (cup) with a sleeve.

  Conventionally, a sleeve (holder) has been widely used for paper or plastic cups, and the cup is inserted into the sleeve for use. The sleeve is often provided with a handle so that the user can easily grip it, but the conventional sleeve is made of hard plastic, and the handle protrudes outward, so that the storage property when not in use is inferior. There was a problem.

  In addition, considering the strength, the sleeve is colored (generally black) and is commercialized, so the sleeve becomes opaque and it is difficult to see how much beverage remains in the cup. Met.

  It is an object of the present invention to provide a sleeve and a cup with a sleeve that are excellent in storage properties when not in use.

The present invention has a cylindrical sleeve body and two incisions formed in the sleeve body, each incision is a curved line and is arranged symmetrically so that both ends face each other. When the portion is pulled out of the sleeve body, two handles are formed, and the window portion is formed in the portion of the sleeve body from which the notch is drawn out.
In the sleeve of the present invention, an opening may be formed in a portion between the cuts of the sleeve body, and the handle may be configured by a portion between the cuts and the opening.
Furthermore, this invention is a cup with a sleeve which has the said sleeve and the cup holding a liquid, and when the cup is inserted in the said sleeve, the side wall of a cup is exposed in a window part.
The side wall of the cup can have transparency, and a plurality of grooves extending from the bottom surface toward the upper end can be formed side by side along the circumferential direction of the cup.
A plurality of protrusions protruding outward from the cup can be formed on the bottom surface of the cup. Each protrusion can be elongated and disposed obliquely with respect to the outer periphery of the bottom surface of the cup. Also, the cup and the sleeve can be made of different materials.

  Since this invention pulls out a handle at the time of use, the storage property of the sleeve at the time of non-use is high. Since the cup and the holder are easily separated, it is easy to take out the cup and the holder for separating resource collection. In use, the side wall of the cup is exposed in the window portion of the sleeve, so that the beverage in the cup can be visually recognized through the window portion.

It is a rear view of the sleeve of this invention. It is a perspective view of the cup with a sleeve of the first example of the present invention. It is a side view which shows the use condition of the cup with a sleeve of a 1st example of this invention. FIG. 4 is a cross-sectional view taken along line AA in FIG. 3. It is a bottom view which shows the state which hold | gripped the cup with a sleeve of this invention. It is a side view which shows the use condition of the cup with a sleeve of the 2nd example of this invention. It is a side view which shows the cup with a sleeve of the 3rd example of this invention. It is a graph which compares the heat retention effect.

FIG. 1 is a rear view showing an example of a sleeve 10 of the present invention. The sleeve 10 has a cylindrical sleeve main body 11, and a cut 16 is formed in the side wall of the sleeve main body 11. The shape of the cut 16 is not particularly limited. For example, the cut 16 has a curved shape that is bent along the outer periphery of a semicircle or a curved shape that is bent along a plurality of sides of a polygon. That is, the cut 16 is a curved line. The shapes and sizes of the notches 16 are substantially equal, and are arranged symmetrically with an interval so that both ends of the curve face each other.
An opening 14 is formed between the two notches 16. Although the number of the openings 14 may be one or two or more, here, the number of the openings 14 is two, and one is arranged inside the curve of each notch 16.

The sleeve body 11 is made of a flexible material such as paper or resin. When the portion between the notch 16 and the opening 14 is pulled outward, the portion is pulled out without breaking, as shown in FIG. In addition, a pair of symmetrical handles 15 is formed, and a large-diameter opening (window portion 19) is formed at a position where the handles 15 are pulled out.
Conversely, when the handle 15 is pushed back toward the sleeve main body 11, the handle 15 becomes flush with the side surface of the sleeve main body 11, so that no space is reserved for storing the sleeve 10. Furthermore, the sleeve 10 can be crushed and flattened, and a plurality of sleeves 10 can be stacked and stored.

  2 is a cup with a sleeve of the first example of the present invention, and the cup with a sleeve 1 includes the sleeve 10 and a cup 21. The diameter of the sleeve body 11 increases from one end to the other end. When the end of the larger diameter is the upper end, the upper end opening is larger in diameter than the bottom surface of the cup 21. To attach the sleeve 10 to the cup 21, first, the cup 21 is inserted into the sleeve body 11 with the bottom surface of the cup 21 facing the upper end opening of the sleeve 10.

The vicinity of the bottom surface of the side wall of the cup 21 bulges outward, and a bulging portion 23 is formed. A plurality of the bulging portions 23 are arranged along the outer periphery of the bottom surface or are ring-shaped along the outer periphery of the bottom surface. The virtual circumference passing through the tip of the bulging portion 23 is the same as or larger than the lower end opening of the sleeve main body 11, and when the cup 21 is inserted, the tip of the bulging portion 23 becomes the sleeve main body. 11 is in contact with the inner wall surface.
Either or both of the sleeve 10 and the cup 21 are made of a flexible material such as resin or paper. When the cup 21 is pushed in with a strong force, either or both of the sleeve 10 and the cup 21 are deformed. Then, the bulging portion 23 passes through the lower end opening of the sleeve main body 11, and the bottom surface of the cup 21 and the bulging portion 23 protrude from the lower end of the sleeve main body 11.

The height from the bottom surface of the cup 21 to the upper end is longer than the length of the sleeve body 11, and the upper end of the cup 21 is the upper end of the sleeve body 11 even when the bottom surface of the cup 21 and the bulging portion 23 protrude from the lower end of the sleeve body 11. It is higher.
The upper end of the cup 21 bulges outward or the upper end side has a larger diameter, and a stopper 22 having a larger diameter than the upper end of the sleeve body 11 is formed. When the cup 21 is further inserted into the sleeve 10, the stopper 22 comes into contact with the upper end of the sleeve main body 11, and the cup 21 is not inserted any more, and the cup 21 is locked to the sleeve 10.

That is, the cup 21 does not fall out of the sleeve 10 due to the stopper 22, and the sleeve 10 does not fall out of the cup 10 due to the bulging portion 23, so that the sleeve 10 is mounted on the cup 21 without using an adhesive or the like. Maintained stably.
Since no adhesive or the like is used, if the cup 21 is pulled upward with a strong force, one or both of the sleeve 10 and the cup 21 are deformed, and the protrusion 23 passes through the upper end opening of the sleeve 10, so that the cup 21 The sleeve 10 is removed. That is, according to the present invention, the sleeve 10 can be easily attached / detached by a human hand even though the state in which the sleeve 10 is attached to the cup 21 is stably maintained during use.

FIG. 3 is a side view showing a use state in which a liquid 41 such as a beverage is put in the cup 21 fitted with the sleeve 10. Normally, in the use state, the handle 15 is pulled out to form the window portion 19, and the side wall of the cup 21 is exposed in the window portion 19. Therefore, when a pattern or the like is printed on the side wall of the cup 21, the pattern or the like can be visually recognized through the window portion 19.
When at least the side wall of the cup 21 is made of a transparent or translucent material and the side wall is transparent, the liquid 41 in the cup 21 can be observed through the side wall of the cup 21 and the window portion 19. It can be seen at a glance whether or not the liquid 41 is contained therein. The window portion 19 has an elongated shape extending from the lower end to the upper end of the sleeve 10, and even when the liquid 41 decreases or increases, the liquid surface can be observed from the outside, and the remaining amount of the liquid 41 can be known at a glance. Yes.

The cup with sleeve 1 of the first example has a plurality of grooves formed on the side wall of the cup 21. 4 is a cross-sectional view taken along the line AA in FIG. 3, and the reference numeral in FIG. Each groove 27 extends from the bottom surface of the cup 21 toward the upper end, and is arranged side by side in the circumferential direction of the cup 21.
Reference numeral 28 in FIG. 4 indicates a protrusion (rib) between the groove 27 and the protrusion 28 is elongated in parallel with the groove 27. The upper end of the cup 21 is wider than the bottom surface, and the taper angle of the side wall is substantially equal to the taper angle of the sleeve body 11. When the sleeve 10 is mounted on the cup 21, the tip of each protrusion 23 extends from one end to the other end. It contacts the inner wall surface of the sleeve body 11. Accordingly, the internal space of the groove 27 is surrounded by the side and bottom surfaces of the groove 27 and the inner wall surface of the sleeve body 11, and when the sleeve 10 is mounted, the air that has entered the groove 27 is sealed.

Outside the window portion 19, the cup 21 is surrounded by the sleeve body 11, so that it does not directly touch the outside air, and the air sealed in the groove 27 functions as a heat insulating material. Is kept hot or cold. Thus, the cup with sleeve 1 of the present invention has a high heat retaining property even if an expensive heat insulating material is used for the sleeve 10 or the sleeve 10 and the cup 21 are not formed in a multilayer structure.
When a cold liquid is put into a conventional cup with low heat retention, condensation occurs on the side wall of the cup due to the temperature difference between the outside air temperature and the liquid. However, the cup with sleeve 1 of the present invention has high heat retention and is difficult to condense. Even if condensation occurs in the portion exposed to the window portion 19, the water droplets gather in the groove 27 and quickly move downward, so that the water droplets do not stay on the side wall of the cup 21 and the sleeve 10 does not get wet.

Next, an example of the bottom shape of the cup 21 used in the present invention will be described.
FIG. 5 is a view of the sleeve-equipped cup 1 observed from the bottom side. A plurality of protrusions 24 protruding outward from the bottom surface are formed on the bottom surface of the cup 21, and the protrusions 24 are arranged at intervals along the outer periphery of the bottom surface of the cup 21.
The shape of the protrusion 24 is elongated. An imaginary straight line extending in the longitudinal direction of the protruding portion 24 through the center of the protruding portion 24 intersects obliquely with a tangent line on the outer periphery of the bottom surface of the cup 21 when the bottom surface of the cup 21 is circular (eg, a perfect circle or an ellipse). In the case of a square (triangle, quadrangle, etc.), it intersects with the outer periphery of the bottom surface diagonally. That is, each protrusion 24 is disposed obliquely with respect to the outer periphery of the bottom surface of the cup 21.

  Usually, when a human places a finger on the bottom surface, the finger is placed perpendicular to the outer periphery of the bottom surface of the cup 21, that is, obliquely with respect to the protruding portion 24 in consideration of easiness of holding and stability. Compared with the case where the finger is parallel to the protrusion 24, the contact area between the finger and the protrusion 24 is reduced when the finger is arranged obliquely with respect to the protrusion 24, so the liquid 21 heats the cup 21. However, the user can hold the cup 21 without feeling much heat.

  Although the case where the groove | channel 27 was formed in the side wall of the cup 21 was demonstrated above, this invention is not limited to this. Reference numeral 5 in FIG. 6 shows a cup with a sleeve according to a second example of the present invention. The cup with sleeve 5 has the same configuration as the cup with sleeve 1 of FIG. 2 except that the groove 27 is not formed on the side wall of the cup 51 and is flattened. Also in this case, if the side wall of the cup 51 is made transparent, the liquid 41 in the cup 51 can be visually recognized. When the material of the cups 21 and 51 and the thickness of the side walls are the same, the strength is higher when the grooves 27 are formed.

  Further, the present invention is not limited to the case where the opening 10 is provided in the sleeve 10. Reference numeral 6 in FIG. 7 shows a cup with a sleeve according to a third example of the present invention. The cup 6 with a sleeve has the same structure as the cup 1 with the sleeve 1 except that the opening is not formed in the sleeve main body 61, and the portion where the notch of the sleeve main body 61 is formed is on the outside. When pulled out, it becomes a handle 65. Since the opening is not formed in the handle 65, the user holds the cup 6 with the sleeve by pinching the handle 65 with a finger. Since the cup 6 with a sleeve of the third example does not need to form an opening but only needs to form a cut, the sleeve 60 can be easily manufactured.

The flexible material used for the cups 21 and 51 and the sleeves 10 and 60 is not particularly limited. For example, it is paper or plastic (resin), and synthetic resin such as polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate (PET), polystyrene or the like can be used as the plastic. These synthetic resins may be used alone or in a combination of two or more.
Among the flexible materials, paper is easy to print. Therefore, if paper is used for the sleeves 10 and 60, patterns, advertisements or explanations are printed on the sleeves 10 and 60, and the cups with sleeves 1 and 5 are printed. Design can be improved. Further, since the paper can be easily formed with the cuts 16, it is also excellent as a material for the sleeves 10 and 60 in that respect.

The material of the cups 21 and 51 is particularly preferably plastic (resin) from the viewpoint of waterproofness. From the viewpoint of transparency, a transparent plastic is particularly preferable, and a reinforcing agent such as a filler can be added to the transparent plastic. The cups 21 and 51 may all be made of the same material, but the bottom surface, the bulging portion 22 and the like may be opaque as long as at least the side wall portion has transparency. Further, the side walls may be colored or provided with a pattern or the like as long as the transparency of the side walls of the cups 21 and 51 is not impaired.
You may provide a scale in the part exposed to the window part 19 of the cups 21 and 51. FIG. In this case, by comparing the liquid level of the liquid 41 in the cups 21 and 51 with the scale, the remaining amount of the liquid 41 can be digitized and visually recognized.

In any of the first to third examples, the sleeves 10 and 60 can be easily attached and detached. Therefore, when the sleeves 10 and 60 and the cups 21 and 51 are made of different materials, the sleeves 10 and 60 can be detached from the cups 21 and 51 after use, and can be taken out as separate resource wastes for garbage collection. For example, many municipalities collect paper, PET (polyethylene terephthalate), and other plastics separately. Therefore, when the sleeves 10 and 60 are made of paper or PET, and the cups 21 and 51 are made of other plastics, the sleeves 10 and 60 are made of other plastics, and the cups 21 and 51 are made of paper or PET. When one of the cup 60 and the cups 21 and 51 is made of paper and the other is made of PET, the cups with sleeves 1, 5 and 6 of the present invention can be easily put out as municipal waste.
In addition, since no adhesive or the like is used for mounting the sleeves 10 and 60, when one of the sleeves 10 and 60 and the cups 21 and 51 is damaged, the sleeve 10 is removed and the damaged one is discarded and damaged. It is also possible to reuse those who do not.

Hot coffee of 77 to 79 ° C. was poured into the cups 1 and 5 of the first and second examples of the present invention, and the temperature difference between the inside and the outside was measured.
The temperature was measured using a digital thermometer (trade name SK-1110SK-SATO, manufactured by Sato Keiki Seisakusho) and two sensors. That is, the coffee in the container was measured with a sensor such as a needle, and the temperature on the side surface of the container was measured by replacing it with a K-type sensor (trade name AD-1217 manufactured by A & D Co., Ltd.).

  The measurement results are shown in the graph of FIG. In addition, the same test was done using the heat insulation cup (trade name SMP-340E by Toagokogyo Co., Ltd.) of the double structure by which the embossed paper was stuck on the outer side as a comparative example. As can be seen from the graph of FIG. 8, the cup 1 with the sleeve of the first example of the present invention has better heat retention than the conventional heat-insulating cup, and can retain heat even without an expensive structure such as a double structure. Is high. Therefore, it can be seen that the groove 27 may be provided when there is a high demand for not only separation and collection performance, storage performance when not in use, but also heat retention.
