Container sleeve

Technical Field

The utility model relates to a container sleeve used for being sleeved on a container such as a coffee cup.

Background

Simple containers such as paper containers are widely used in convenience stores, restaurants, and the like for selling food. Since simple containers such as paper containers cannot be said to have sufficient heat insulation properties, when such containers are sold by filling hot or cold beverages (for example, coffee, black tea, soup, tea drink, soft drink, shaved ice, etc.) with the containers, consumers who buy the containers with the beverages or the beverages in the containers may feel uncomfortable by transferring cold or heat to their hands and may be burned. Therefore, in order to improve the heat insulation between the container and the hand, a container sleeve is used which is fitted to the side wall of the container.

Detailed Description

Fig. 1 shows an embodiment of a container cover 1 according to the present invention, and the container cover 1 is formed in a ring shape that is fitted around the outer periphery of a side wall 5 of a container 4 as shown in fig. 2. The container 4 is generally formed with a curled portion 6 at an opening portion. The upper end edge 2 and the lower end edge 3 of the container cover 1 of the present embodiment are formed in a waveform in which a plurality of curved recesses and protrusions are continuous.

The waveform of the upper end 2 and the waveform of the lower end 3 of the container cover 1 may be the same waveform such as the height of the projections and depressions, the pitch of the projections and depressions, and the shape of the projections and depressions, or may be different waveforms such as the height of the projections and depressions, the pitch of the projections and the shape of the depressions and the depressions. The waveform of the upper edge 2 and/or the waveform of the lower edge 3 may be a waveform in which the same irregularities such as the height of the irregularities, the pitch of the irregularities, and the shape of the irregularities are continuous, or a waveform including irregularities having different heights, pitches, and shapes.

The waveform shape is not limited to the shape in which the curved irregularities are continuous as shown in the container cover 1 of the above embodiment, and may be a waveform composed of linear irregularities such as a waveform composed of rectangular irregularities or triangular irregularities, or may be a waveform including both curved irregularities and linear irregularities.

The height of the waveform (the length between the convex portion and the concave portion of the concavity and convexity) is preferably 1mm to 15 mm. The pitch of the waveform is preferably a pitch in which a plurality of projections and depressions can be formed, and preferably a pitch in which at least three sets of projections and depressions are formed. Preferably, the positions of the wave-shaped convex portions of the upper end side 2 and the positions of the concave portions of the lower end side 3 of the container cover 1 substantially correspond to each other. The height H of the container cover 1 (the length between the top of the convex portion on the upper edge and the top of the convex portion on the lower edge) is not particularly limited as long as the height does not interfere with the fitting of the container cover 1 to the side wall of the container 4, but is preferably shorter than the length L of the side wall 5 of the container 4, and from the viewpoint of easy holding when the container 4 is held by hand with the container cover 1 in between, the height H of the container cover 1 is preferably 20mm or more and the length L of the side wall 5 of the container 4 is preferably about 1/3 or less. The container cover 1 is preferably formed to have a diameter such that the upper edge 2 is positioned below the lower end of the curled portion 6 of the opening of the container 4 and is fitted over the container side wall 5.

Fig. 3 is a view schematically showing a method of taking out a blank 7 from a roll for forming a container jacket having waves of the same concavo-convex shape, height, and pitch at the upper end edge 2 and the lower end edge 3. The blank 7 is fitted to the side wall 5 of the container 4 formed in an inclined shape by the side wall 5 shown in fig. 2, and the blank 7 is formed in a fan shape, and is formed in a circular shape by joining the left and

right ends

8a and 8b of the blank 7, so that the blank is fitted into the container 4 formed in an inclined shape by the side wall 5. The blank 7 can be taken out from the roll. As shown in fig. 3, when the blanks 7 adjacent to each other, for example, the waveform of the lower end edge 3a of the blank 7a and the waveform of the upper end edge 2a of the blank 7b adjacent to the blank 7a are taken out so as to be butted waveforms when taken out from the roll, the butted waveform portion is shared by the lower end portion of one blank 7(7a) and the upper end portion of the other blank 7(7b), and therefore the amount of the roll material used for the blanks 7 can be reduced, and the waste of the taken material between the blanks 7 can be reduced.

The material for taking out the blank 7 forming the container cover 1 may be a pulp-based material, a fiber-based material, a synthetic resin-based material, a metal-based material, a wood-based material, a glass-based material, or a composite thereof. As the web, for example, in addition to so-called paper sheets manufactured by binding together plant fibers and other fibers, corrugated paper, chemical fiber paper, synthetic paper, water-resistant paper, coated paper, substitute paper, parchment paper, wool paper, glass fiber paper, and the like can be cited. Further, a so-called airlaid sheet formed by combining pulverized pulps piled up by an air flow into a sheet, a pulp-based material, a natural fiber material, a nonwoven fabric of fibers such as synthetic fibers, or the like can be used. Further, films or sheets of synthetic resins, natural resins, biodegradable resins, foamed sheets, metal foils such as aluminum foils, wood foils, and the like, or composites thereof can also be used as the roll stock. The material, thickness, and the like of the web are not limited as long as the web can be subjected to removal processing by punching or the like, and the web is generally preferably a film-like or sheet-like material, and is preferably a paper-like material, a pulp-like material, a resin film material, a sheet material, a metal foil such as an aluminum foil, or a laminate thereof. Among them, paper and other materials containing pulp materials are preferable, and paper or materials having a coating layer of synthetic resin such as Polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), biodegradable resin such as polybutylene succinate (PPBS), polyvinyl alcohol (PVA), polylactic acid (PLA) or the like on one surface or both surfaces of paper are preferable.

Since the container sleeve 1 formed of the fan-shaped blank 7 is formed in a shape in which the side wall of the container sleeve 1 is inclined, the volume when a plurality of container sleeves 1 are stacked one on top of another and stored can be reduced as shown in fig. 4, and the storage space can be reduced.

In the case where the container sleeve 1 of the present invention has an inclined side wall, a plurality of container sleeves can be stacked and distributed as described above, and the container sleeve 1 can be distributed and stored in the form of the sheet stock 7, and can be used after the left and

right end portions

8a and 8b of the sheet stock 7 are joined to each other to form the container sleeve 1. The product obtained by joining the left and

right ends

8a, 8b of the sheet blank 7 can be distributed and stored in a state crushed into a flat plate shape. In the case of a container sleeve formed of a square blank and having a non-inclined side wall, the container sleeve can be stored and distributed in a blank state, or can be stored and distributed in a state of being crushed into a plate-like shape, and the distribution and storage space can be effectively utilized.

The container cover described above shows a case where both the upper end edge 2 and the lower end edge 3 are formed in a wave shape, but only one of the upper end edge 2 and the lower end edge 3 may be formed in a wave shape. In the case of such a container sleeve, the reduction rate of the amount of the web material is about half as compared with a container sleeve in which both sides of the upper end edge 2 and the lower end edge 3 are formed in a wavy shape, but the amount of the web material used can be reduced as compared with a conventional blank for forming a container sleeve. In the case of taking out a sheet blank having only one of the upper end edge 2 and the lower end edge 3 formed in a wavy shape from a roll stock, the lower end edge of one sheet blank is taken out in a manner of abutting the upper end edge of the sheet blank taken out adjacent to the sheet blank in a wavy shape, and therefore, it is possible to manufacture substantially the same number of container sleeves having a wavy shape only at the upper end edge and container sleeves having a wavy shape only at the lower end edge from one roll stock.

The container cover 1 of the present invention may be printed on the surface, and subjected to surface hydrophobic treatment, surface gloss treatment, embossing, and the like.
