Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is applicable to foodstuffs in supermarkets or shops.
Regarding containers for small items.

Conventional technology Instant foods, tsukudani, natto, prepared foods, confectionery, etc. are subdivided into cups and sold side by side on the supermarket shelves in a packed state. Packed products have grown significantly because they are no longer used. The number of households is decreasing and subdivided into 1 person, 2 persons or 1 meal, 2 meals are displayed according to the needs. If you want to group multiple items, bundle them with rubber bands or shrink wrap It is on display. When such containers are stacked and displayed on the shelves in two or three steps, it is unstable, and even if the customer touches the product for a while, it may be dropped sideways, which is not preferable for product management. Further, when packaging a plurality of packages, there is a problem that the containers are not connected and the packages are disjointed, which requires labor for packaging and is difficult to handle even after packaging. The one that was considered for this problem is Jitsukai Sho 53-95345.

The problem to be solved by the invention is that the lid has an annular protrusion on the bottom of the container so that the lid and the container are engaged with each other between the lids which are in contact with each other. An annular groove is provided for fitting. However, since it is a mere concavo-convex fitting, if the fitting is loose, the upper one is merely placed, so that it is inconvenient because it will fall down when a hand or the like touches it. Therefore, when the container is manufactured, the fitting tolerance between the protrusion and the groove is important, and there is a problem in cost increase and process management due to manufacturing of the mold and management of sheet unevenness.

The present invention has been made in view of the above problems of the prior art, and it is an object of the present invention to provide a resin container which is firmly connected by a bite fit and which can be stacked without being easily collapsed.

Means for Solving the Problems A cup-shaped cylindrical container made of foamed beads, and a bottom portion of another cup-shaped container made of foamed beads that is fitted and capped on the opening of the cup-shaped cylindrical container. Engagement portions consisting of a group of one or several lines having a same or substantially the same diameter of a recess that can be fitted and having leads in the same direction protruding on the inner wall peripheral surface of the recess are provided at several positions in the circumferential direction. And a lid made of a thermoplastic resin provided on the container. The lid and the container are connected by swirling while pushing the bottom of the container into the recess of the lid.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. The cup-shaped container 1 that is made to a size according to the quantity is usually a foamed bead of styrene, polyethylene, polypropylene or the like or a molded product of an equivalent material,
It is slightly tapered to make it easy to separate from the shape and has a conical shape that opens on the mouth side. An outer burr and a collar portion 1a are formed on the rim for reinforcement. The lid 2 to be capped with this is made of a thermoplastic resin and has a bent portion 2a of a short cylindrical shape that is tightly fitted to the collar portion 1a of the opening of the cup-shaped container 1 and is formed at the outer edge so that it can be easily folded. The end 2f is formed so as to open outward, and one or several protrusions 2b are formed at several locations from the outer peripheral portion of the upper surface to the outer side of the shape that also serves as reinforcement for the bent portion 2a, If necessary, the cup-shaped container 1 is slightly inwardly protruded so as not to come off easily, so that the cup-shaped container 1 is bitten into the collar portion 1a of the rim. Further, a concave portion 2c having the same shape as the cup-shaped container 1 and having a bottom portion tightly fitted therein is formed in the central portion of the upper surface of the lid 2, and one or several strips having the same lead angle in the same direction are formed on the inner peripheral portion. The ridges 2d are formed at several places around the circumference so as to dig into the outside of the bottom of the container. As another embodiment of the protrusion 2d, one point-like protrusion protruding inwardly on the inner peripheral portion, for example, a spherical protrusion 2d 'can be used, but a quadrangle whose diagonal line is the center line of the lid and the circumferential direction. The diamond shape is preferable.

Action For example, one serving of natto is packed in the cup-shaped container 1 and the lid 2 is covered and pressed strongly, so that the bent portion 2a at the outer edge of the lid 2 is cup-shaped container 1
Tightly fit and tightly engage the collar portion 1a at the edge of the. In this way, the cup-shaped container 1 with the natto packed and the lid 2 covered is, for example, 1
The required number, such as 3 meals per day or 2 meals per person for 2 persons, is placed on the concave portion 2c of the lid 2 of the first container 1 and the bottom of the second container 1'is placed second.
Stack the bottom of the third container over the recess in the lid of the container. When stacking, in the case of the previous embodiment, the protrusion 2d in the recess 2c
Push it while twisting in the direction of the lead so that it bites properly into the outer circumference of the bottom of the container. The ridge 2d of the lid 2 made of a resin that becomes harder after molding makes the outside of the container 1'recessed in the lead direction because the container 1'is formed by bead foam molding that can be dented with a little strong force. In addition to the fitting between the bottom and the bottom, the concave and convex engagement further strengthens the connection. In this case, the operation is easy.

Further, in the case of the latter embodiment, since it is a spherical or diamond-shaped point projection, the bottom of another container 1'is pushed straight into the recess 2c of the lid 2 of the container 1 and then swung slightly after the bottom is attached. In this case, since the recess formed by the protrusion 2d 'is bent in the circumferential direction from the axial direction to the key, the recess is not disturbed and is reliable.

In this way, the containers covered with the lid 2 are stacked in two or three layers, and if necessary, the whole is put together in a shrink wrap or the like.

Although the recess of the lid has been described as a size that fits the bottom of a container of the same shape, this may be combined in order as a recess of a size that fits the bottom of a container of another size. Of course you are free.

Effect As described in detail above, the present invention has a recess of the same diameter or substantially the same diameter that fits with the bottom of a cylindrical container made of other bead foam molding in the center view of the upper surface of the lid made of thermoplastic resin. A protrusion having leads in the same direction is formed on the inner wall surface of the recess, and the protrusion is swung while pushing the bottom of another container into the recess so that the protrusion can be engaged with the soft container. Therefore, it is suitable for display at supermarkets etc. even if you touch it a little even if you touch it even if you do not wrap it, it is suitable for display at supermarkets etc. It is very convenient because the number of stages can be easily taken out and no selection time is required. In addition, since they are securely connected, the work of shrink-wrapping several pieces is easy, and the products are easy to handle. Further, it has an effect that it is convenient for packaging such as transportation of appropriate products.
