Description

[Detailed description of the invention] This invention mainly relates to a cap that is removably fitted onto a pourer that stores instant adhesive.In particular, a drying agent is attached to the inner end of the cylindrical peripheral wall to prevent the adhesive from curing. The present invention relates to a synthetic resin cap having a storage section for storing things.

Conventionally, as shown in FIGS. 1 and 2, for example, a cap 2 that is removably fitted onto an instant adhesive dispenser 1 has a vertically long cylindrical shape with an open lower end and a closed upper end, similar to the cap of a writing instrument. It has a solid storage part 4 at the innermost end of the cylindrical peripheral wall 3, that is, at the upper end of the interior, in which a drying agent (a large number of granular drying agents are collected to form one suitably sized piece) A solid object) 5 is stored in such a way that it is pushed in from the bottom end.

By the way, as shown in FIGS. 1 and 2, the solid storage portion 4 deep inside the peripheral wall 3 of the cap 2 has a plurality of vertical ribs 6 on its inner peripheral surface at equal intervals in the circumferential direction. The drying agent 5 was pushed in so as to be pressed by these vertical ribs 6.

However, since the vertical ribs 6 each protrude toward the center of the cylindrical peripheral wall 3 and do not undergo elastic deformation, the periphery of the drying agent 5 may collapse or crack when the drying agent 5 is pushed in. However, there is a drawback that the drying agent 5 is not held under pressure and falls off.

Further, as shown in FIG. 3, as a conventional one, a transverse rib 7 having a semicircular cross-section in the circumferential direction is provided on the innermost end of the peripheral wall 3 of the cap 2 in front of the solids storage part 4 in order to reduce the inner diameter thereof. However, like the above embodiment, this does not deform, so when the drying agent 5 is pushed in, the periphery of the drying agent 5 may collapse or crack, causing damage to the storage area at the back. Even if it was placed within 4, it still had the drawback of rattling and falling off.

This idea was devised in view of the above circumstances, and its purpose is to store solid materials such as drying agents in the storage area at the innermost end of the cylindrical peripheral wall without causing the surrounding area to collapse or crack. To provide a cap which can be pushed and stored, and which can securely store and hold solid objects by preventing them from rattling, playing, and falling off in the stored state.

In other words, the cap of this invention has a plurality of elastic ribs that protrude in the shape of horizontal ribs from the inner circumferential surface of the circumferential wall at intervals in the circumferential direction on the front side of the solid matter storage section at the innermost end of the cylindrical circumferential wall. Deformable solid non-return tongues and a plurality of elastically deformable solid non-return tongues protruding from the inner circumferential surface of the circumferential wall between these non-return tongues in a gob shape, each inclined with respect to the diameter direction of the circumferential wall. When a solid object such as a dry agent is pushed in, each non-return tongue piece is elastically deformed so as to escape and bend, allowing the solid object to overcome the non-return tongue piece and push it deep inside. When the solid object enters the storage section and is stopped from being removed, at the same time, the vertical rib-like solid object pressure piece that is tilted multiple times elastically deforms in response to the solid object entering, and the solid object is appropriately pressed without breaking or cracking the solid object. This allows it to be held and stored under pressure.

An embodiment of this invention will be described below with reference to FIGS. 4 to 6.

In the figure, reference numeral 12 designates a cap made of a one-piece synthetic resin product having the same form as the one in FIG. A solid substance 15 such as a drug is pushed into the housing.

Here, the solid matter storage portion 14 at the innermost end of the cylindrical peripheral wall 13 is
Three solid non-return check tongues 16 projecting in the shape of horizontal ribs from the inner peripheral surface of the peripheral wall 13 at equal intervals in the circumferential direction are integrally molded at the front side of the peripheral wall 13. ing.

Each check tongue piece 16... is connected to the peripheral wall 13 as shown in FIG.
They are flat and oblong, each with an opening angle of 60 degrees in the circumferential direction, and each has a thin cross section and a slightly U-shaped curve from the outer end toward the inner peripheral edge, as shown in Figure 4. Each of these has a structure that can be elastically deformed so that the inner end seams escape upward in response to a pressing force from below.

Further, on the inner circumferential surface of the solid material storage portion 14 at the innermost end of the cylindrical peripheral wall 13, there are two strips of check tongues 16 at equal intervals in the circumferential direction between each of the non-return tongues 16. Each of the elastic pressure pieces 17,17 is integrally formed to protrude from the lower end to the upper end of the check tongue piece 16 in a vertical rib shape.

Each of these elastic pressure pieces 17 has a thin plate-like cross section, and projects from the inside to the outside by being inclined at an angle θ (for example, about 20 degrees) with respect to the diametrical direction of the peripheral wall 13, as shown in FIG. It has a structure that can be elastically deformed as shown by the imaginary line when pressed.

Incidentally, the radius R1 of each inscribed circle of the above-mentioned pressure pieces 16... is smaller than the outer circumferential radius R of the solid object 15 such as a dry drug to be stored, and the inscribed circle of the above-mentioned non-return tongue pieces 16... The radius R2 of the circle is set to be smaller than the radius R□ of the elastic pieces 16.

In the cap configured as described above, when a solid object 15 such as a dry agent is pushed into the upper inner storage part 14 from the open lower end side with a finger or the like, as shown in FIG. The vertical rib-shaped elastic pressure piece 17... slides into contact with the lower end tapered part, elastically deforms the pressure piece 17 outward, and moves forward, so that the non-return tongue piece 16... The check tongue pieces 16 come into contact with each other and move over the check tongue pieces 16 while elastically deforming the inner peripheral edges thereof so as to press and bend them upward.

At this time, the solid material 15 does not collapse or crack around the solid material 15 at all.

As a result, the solid object 15 enters the storage portion 14 as shown by the imaginary line in FIG. It is held in pressure contact with the periphery by each elastic pressure piece 17, so that it can be reliably stored and held without any looseness or play.

Since this device has been developed as described in detail above, it is possible to conveniently push and store solid materials such as drying agents into the storage portion at the innermost end of the cylindrical peripheral wall without the surrounding area collapsing or cracking. At the same time, it is possible to reliably prevent the solid objects from rattling, playing, or even falling off while in the stored state.
