Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is a vacuum-formed product made of film-like resin, and is mainly used for packaging a plurality of eggs in a container for distribution such as transportation or display sales. More specifically, it relates to a multi-layer container in which a plurality of articles stored in one plane are packaged as a unit, which are then packaged in two layers.

<Prior Art> Conventionally, there has been no dedicated container that can package multiple items stored in one plane in a single container in a layered manner.

However, as such a multilayer packaging means, as shown in FIG. 6, a container member 01 having a rectangular shape in plan view
both vertically and horizontally (this is to illustrate with an egg container,
A plurality of article storage recesses 01 are spaced apart in one direction depending on the article to be stored.
A, and a plurality of containers each having a semi-concave portion 01A′ corresponding to two halves of the concave portion 01A formed on the outer periphery along two adjacent sides,
By stacking them alternately by flipping them 180 degrees,
A recess 01B that corresponds to and opens in the opposite direction to the recess 01A in the lower container is formed between adjacent recesses 01A in the container, and each article is accommodated between the upper and lower opposing recesses 01A and 01B, respectively. Packaging means of the form are known.

<Problems to be Solved by the Invention> In the case of the above-described conventional multilayer packaging means, the upper half storage recess 1B of the article stored in each recess 01A in the lower container is connected to each recess 01A in the upper container. Since it can be formed between adjacent containers, a lid body having a recess for storing the upper half of the article is provided separately from the container member 01, and both constitute a single container, and the unit containers with lids are stacked. Although it has the advantage of being able to be packaged in low-volume multi-layered packaging and is very efficient in terms of storage efficiency, the only items that can be carried, etc. in a single container are those that contain multiple single-layered items stored in one plane. Moreover, if the product is handled in a single container, the upper half of the product remains exposed, which is unfavorable in terms of packaging performance. It is also possible to handle three containers in a stacked state in order to carry two layers at once, but since the three containers are physically separated, one of them may unexpectedly fall off and cause damage to the product. There is a risk of causing damage, and even though it is useful for mere display and sales, it is very inconvenient to carry, especially for handling by buyers.

<Means for Solving the Problems> In view of the above circumstances, the present invention has high accommodating efficiency,
Moreover, the object is to provide a device that can safely and conveniently handle a plurality of articles stored in layers.

In order to achieve the above object, the multilayer container according to the present invention has a first container member that is rectangular in plan view and has a plurality of article storage recesses spaced apart in both the vertical and horizontal directions, or in either direction. The first container member is stacked on one side of the first container member by swinging around a bent portion formed along the outer side portion as a fulcrum, and the first container member is unfolded laterally. and a plurality of article storage recesses located between adjacent recesses in the first container member in the stacked orientation, and a plurality of article storage recesses located between adjacent recesses in the first container member. a second container member forming a recess opening in the opposite direction corresponding to the recess in the first container member;
The other side of the first container member has a posture in which it is stacked on the second container member by swinging around a bend formed along the side, and a side of the first container member. A configuration in which a third container member is integrally connected to the third container member, which can freely switch between the opened position and the stacked position, and forms a recess opening in the opposite direction to the recess in the second container member in the stacked position. It has the following characteristics.

<Function> When using the multilayer container according to the present invention having such a characteristic configuration, the second container member and the third container member are respectively deployed on both sides of the first container member. First, articles are stored in each recess in the first container member in the same posture, and then the second container member is swung through the bending portion to switch to the stacking posture on the first container member, The upper half of the article stored in each of the recesses is stored in a recess that opens in the opposite direction and is formed between adjacent recesses in the second container member. After storing the articles in each of the concave portions of the second container member, the third container member is swung through the bending portion to switch to the stacking posture on the second container member. The upper half of the article stored in each of the recesses in the second container member is stored in the reversely open recess in the third member. By this,
It is possible to store and package a plurality of articles in two layers in a single container, with each layer completely surrounding the opposite recesses, and such multi-layer (double-layer) packaging is also possible. It can be carried in its original form and displayed and sold. Contrary to the above, the articles stored in each layer can be taken out by sequentially swinging and unfolding the third container member.

<Example> Hereinafter, an example of the present invention applied to an egg container will be described in detail based on the drawings.

1 to 4, reference numeral 1 denotes a first container member having a rectangular shape in plan view, in which a plurality of egg storage recesses 1A are formed at appropriate intervals in both the vertical and horizontal directions, and adjacent A half-recessed portion 1A' corresponding to approximately two halves of the recessed portion 1A is formed on the outer periphery along the two sides of the recessed portion 1A.
A conical protrusion 1C and a semi-conical protrusion 1C' are respectively formed at the same wall meeting point of the semi-concave part 1A'.
Furthermore, a series of small circular projections 1c and small semicircular projections 1c' are integrally formed on the upper end surfaces of these projections 1C and 1C'. Reference numeral 2 denotes a second container member having approximately the same size and shape as the first container member 1 in plan view, and a second container member 2 having a side portion on one of a pair of opposing side portions of the first container member 1. By swinging around the integrally formed bending part 4 along the side part, the first container member 1 is stacked in the stacked position as shown in FIG. 3, and the side of the first container member 1 as shown in FIG. The first container member 1 can be freely switched to a position in which it is unfolded in the opposite direction, and at appropriate intervals in both the vertical and horizontal directions, there is a space between adjacent concave portions 1A in the first container member 1 in the stacked position. The protrusion 1C
A plurality of egg storage recesses 2A are formed in the first container member 1, the bottoms of which are in contact with each other, and along two sides different from the two sides existing in the semi-recess 1A' of the first container member 1. A semi-concave portion 2A' is formed on the outer periphery of the pipe, and the bottom surface thereof is in contact with the semi-conical protrusion 1C' of the first container member 1 in the stacked posture. There are small circular protrusions 2c at each peripheral wall meeting point.
A conical protrusion 2C with a protruding shape and a semi-conical protrusion 2C' with a semicircular small protrusion 2c' protruding from each other are formed, and the first container member 1 is formed on the bottom surface of each of the recesses 2A and semi-concave parts 2A'. Small protrusions 1c and 1 in
Small recesses 1d and 1d' are formed to fit into c', respectively. The conical protrusion 2C located between the concave portion 2A and the semi-concave portion 2A' in the second container member 2 corresponds to each concave portion 1A in the first container member 1. It is configured to form a concave portion 2B that opens in the opposite direction. Reference numeral 3 denotes a third container member having substantially the same size and shape as the first and second container members 1 and 2 in plan view, and a pair of opposing side portions of the first container member 1. On the other hand, by swinging around the integrally formed bending part 5 along the side part,
It is possible to freely switch between the posture in which the second container member 2 is stacked as shown in FIG. 4 and the posture in which the first container member 1 is expanded to the side as shown in FIG. At the separated portions, the bottom surfaces contact the conical protrusion 2C and the semi-conical protrusion 2C' of the second container member 2 in the stacked position, respectively, and the recess 2A of the second container member 2 is formed. A recess 2B corresponding to and opening in the opposite direction.
A recessed portion 3A is formed between adjacent portions.

Thus, the first container member 1 and the second container member 2
The swinging bending portion 4 is formed in the shape of a wide band that protrudes laterally outward, and is located on the side of the third container member 3 opposite to the side on which it is connected to the first container member 1. has a wide band-shaped folded part 3D that overlaps the wide band-shaped folded part 4 in the stacked posture,
A hand portion 6 is formed by providing a hole in the wide band-shaped folded portion 3D and the wide band-shaped folded portion 4 that overlap each other to the extent that the palm of the hand can fit therein.

In addition, the above first, second and third container members 1, 2
and 3 are integrally constructed by one-shot vacuum forming of a single film-like resin material. Also,
On the surface of the third container member 3, it is possible to attach a picture pattern or display characters of various items by printing or pasting a label.

FIG. 5 shows another embodiment, in which the first container member 1, the second container member 2, and the third container member 3
A plurality of groove-shaped recesses 1A, 2A, and 3A are formed at appropriate intervals along only one direction of the containers, and such a container is suitable for relatively long containers such as yokan or bamboo rings. Used for multi-layer packaging of products.

<Effects of the Invention> As is already clear from the detailed description above, the present invention provides: (a) three container members 1, 2, and 3, namely the first, second, and third container members; It is possible to use a two-layer packaging format in which multiple items are stored in each layer, with the items in each layer being misaligned with each other, so a similar two-layer packaging format can be created using two containers with lids. Not only can the ratio of the storage capacity to the container material be increased to improve the storage efficiency, but also (b) the entire package can be bulky and multi-layered packaging.

(c) Furthermore, since the container members 1, 2, and 3 are connected together, the container can come apart not only during static handling such as display and sale, but also during dynamic handling such as transportation. There is almost no need to worry, and handling in multilayer packaging can be carried out safely and conveniently throughout distribution.

This resulted in extremely excellent effects.
