Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a portable case in which a granular material for cooling is put and used for dispensing.

(Prior Art) As a case for putting and using a granular material for cooling and the like for dispensing, for example, a case in which a dispensing hole provided in a case body is opened and closed by a slidable lid is conventionally known. ing.

(Problems to be solved by the invention) In the conventional case in which the dispensing hole is opened and closed by the slide lid, the number of parts is large and the cost is high, and it is difficult to provide the hole at the corner due to the structure. ,
Usability is not sufficient.

The present invention has been made in view of the above problems, and an object of the present invention is to obtain a dispensing case for a granular material which has a small number of parts, is low in cost, and has good usability.

(Means for Solving the Problems) In a card case according to the present invention, a rectangular tray-shaped bottom member and a lid member are fitted together to form projections and depressions on a plurality of sets of bosses provided on the inner surfaces of the bottom member and the lid member. A card-shaped case assembled by combining the lid member with one corner of the lid member as a hinge cap integrated with the lid member, and a lower edge of a side wall portion of the hinge cap being a protrusion provided on the bottom member. This is a card case with a hinge cap that is fitted so as to be openable and closable.

In the above case, the boss on the side of the bottom member is formed with a recessed hole having a reduced diameter portion, while the boss of the lid member is a boss with an undercut that fits into the recessed hole and is locked to the reduced diameter portion. Good to do.

Further, in order to improve the assemblability, five sets of bosses that are fitted in the concavo-convex are provided, and the bosses on the lid member side of the two sets of bosses on the diagonal line are made higher than the bosses on the other lid member side. It is preferable that the diameter-reduced portion of the recessed hole of the corresponding boss on the bottom member side is made lower than the diameter-reduced portion of the other recessed hole, and the positioning is performed by these two sets of bosses.

Also, to ensure that the hinge cap can be held at a predetermined closed position, the side wall of the hinge cap integral with the lid member is extended in an arcuate shape so as to cover the side surface of the corner of the lower member when the lid is closed. Then, a plurality of protrusions are formed on the inner surface of the side wall portion on the base end side, and the lower edge of the side wall portion of the hinge cap is fitted to the side surface of the corner portion of the bottom member corresponding to the hinge cap when the lid is closed. It is advisable to provide a protrusion that locks the hinge cap at the center position in the thickness direction of the case by abutting on the protrusion.

Also, due to the molding accuracy and deformation after molding, the dimensional relationship between the heights of the edges of the bottom member and the lid member and the height of the boss varies, which creates an undesired gap between the edges. On the contrary, in order to prevent the boss from being loosely fitted, a step-up portion is provided on the inner surface side of the side wall end edge of the bottom member, and at the inner surface side of the side wall end edge of the lid member. Providing a step-down part shallower than the height of the step-up part by a predetermined dimension, the step-up part and the step-down part are engaged with each other when the case is assembled, and a minute gap is formed between the edges of the bottom member and the lid member. It is preferably configured to be formed.

(Operation) In the card case of the present invention, the bottom member and the lid member are assembled by concave and convex fitting of a plurality of sets of bosses, and one corner portion of the lid member is a hinge cap integral with the lid member. Since the lower edge of the side wall part is openably and closably fitted to the ridge provided on the bottom member, the structure is simple and the number of parts is reduced. The hinge cap can be easily opened and closed without opening, and the contents can be dispensed from the corners of the case, improving usability. Further, since the outer shape is thin and smooth when the lid is closed, portability is improved.

Since the bottom member and the lid member are assembled by the concave and convex bosses having the reduced diameter portion and the bosses with the undercuts, the simple and reliable assembly is possible. Further, by providing 5 sets of bosses and making the bosses on the lid member side higher than the other 2 sets, the positioning is facilitated and the assemblability is improved.

In addition, the side wall of the hinge cap is extended in an arc shape in cross section,
A plurality of protrusions are formed on the inner surface of the side wall portion on the base end side, and a protrusion is provided on the bottom member side for fitting the lower edge of the extended side wall portion of the hinge cap and contacting the protrusion. As a result, the hinge cap is securely locked at the center position in the thickness direction of the case.

Further, the step-up portion of the side wall end edge of the bottom member and the step-down portion of the side wall end edge of the lid member are engaged with each other to form a minute gap between the bottom member and the end edge of the lid member. By doing
Even if there is a variation in the dimensional relationship between the height of the edges of the bottom and lid members and the height of the boss due to molding precision or deformation after molding, the boss can be reliably maintained with a small gap between the edges. Fit together.
