Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to various deformable containers filled with food and drink such as pudding, for example, and a container having a concave portion or the like on a part of its inner wall surface to facilitate the removal of the food and drink.
[0002]
[Prior art]
Such a deformable container filled with food and drink such as pudding in the prior art is shown in FIG. If the said technique is demonstrated, 1 is a container main body, and food and drinks 2, such as pudding, are filled in the inside. The opening 3 is formed in a substantially square shape and has four vertical side surfaces 4. Further, the bottom surface (lower surface) 5 is formed so as to project a series of return-shaped clogs 7 so that the bottom surface 5 is not in direct contact with the container body 1 when placed on a table or the like. A projecting piece (pocketing part) 6 is projected and integrally formed on a part of the bottom surface 5, and the peripheral part of the projecting piece 6 is a thin bottom surface part 5 a.
[0003]
The conventional technology has such a configuration, and when the food and drink 2 such as the pudding is taken out from the container main body 1, if the projecting piece 6 is bent as shown by a one-dot chain line, the direction of the projection 6 in the direction of arrow A is as follows. The above-mentioned food and drink 2 are released by flowing outside air through a through hole 5b formed by cracking the thin portion 5a of the bottom surface 5 by the bending operation.
[0004]
Further, as another example in the prior art, there is a structure in which the bottom surface 5 of the container body 1 has no protruding piece 6 at all. In the case of the container having such a structure, when the food and drink 2 such as the pudding is taken out from the container main body 1, the container main body 1 is largely deformed by applying a strong external force to release the food and drink 2. .
[0005]
The bottom surface 5 of the container body 1 is provided with a series and ring-shaped clogs 7, and as described above, when taking out the food and drink 2 such as the pudding from the container body 1, the container body 1 is more powerful against the clogs 7. The container body 1 is deformed by applying an external force, and the food and drink 2 is released.
[0006]
[Problems to be solved by the invention]
Since the conventional technique has the configuration described above, the following problems existed.
A protruding piece 6 is provided on a part of the bottom surface 5 of the container body 1, and the protruding piece 6 is used when the container body 1 is accumulated in the production process or when the container 2 is transported to a filling user of food and drink 2. The thin portion 5a of the bottom surface 5 formed around the projecting piece 6 and the projecting piece 6 may be cracked or broken. In this case, crack holes, pinballs, and the like were also generated.
[0007]
If the protruding piece 6 of the thin portion 5a of the bottom surface 5 is cracked or broken, and if a pinhole is generated, a food or drink 2 such as pudding filled in the container main body 1 may have a hole or In the process of leaking from the pinhole and filling the container body 1 with food and drink 2 such as pudding, the already filled food and drink 2 flows out of the container body and hinders the process function of the production process line. Also, product quality issues were raised.
[0008]
Furthermore, in the process of filling the food and drink 2 into the container body 1, the protruding piece 6 may be broken, and the protruding piece 6 may be mixed into another container body. In such a case, if a foreign product is mixed in the food and drink 2 such as pudding and the product is put on the market as a product, there is a concern that a complaint will be generated from a general consumer and that a so-called PL lawsuit will be developed.
[0009]
When the food and drink 2 filled from the container body 1 is taken out, it is necessary to bend the protruding piece 6 provided on the bottom surface 5 of the container main body 1 first. There are cases where the consumer performs directly with fingers or with a tool such as a bending tool. In the former case, when the person is a person without a finger, such as a woman, an elderly person or a child, the bending operation of the protruding piece 6 is performed. There is a problem that the consumer is unable to provide food and drink such as pudding when there is no such tool.
[0010]
When there is no protruding piece 6 or outside air inlet on the bottom surface 5 of the container body 1, it is difficult for the consumer to release the food and drink 2 filled in the container body 1 from the container body 1. The product value was reduced.
[0011]
The bottom surface 5 of the container body 1 has a series of annular clogs 7, and the bottom surface of the container body 1 is used to release the food and drink 2 filled in the container body 1 from the container body 1. The clogs of the clogs 7 also need to be deformed by applying a strong external force. However, the clogs 7 having the above structure are difficult to deform and it is difficult to release the food and drink 2 from the container body 1. It was.
[0012]
The structure of the container according to the present invention is such that a recess is formed on a part of the inner wall surface of the container body without forming a protruding piece (pocketing part) on the bottom surface of the container body, and the clogs of the bottom surface of the container body are extracted. The purpose of the present invention is to make it possible to easily take out food and drink such as pudding from the container body and provide it to consumers with relatively weak fingers and arm strength. .
[0013]
