Description

  The present invention relates to a composite container for adhesive.

  As a conventional composite container for adhesives, there is known an adhesive composite container composed of an aluminum container for containing an adhesive and a resin outer container for holding the aluminum container.

  With conventional composite containers for adhesives, it is difficult to precisely adjust the discharge rate of adhesives, and it is difficult to quantitatively use adhesives in aluminum containers. Since some of the agent could not be discharged and remained in the container, these improvements were desired.

In response to these demands, the present inventors previously (1) a composite for adhesive in which a window hole for directly pressing an aluminum container to be accommodated with a finger is formed on one side wall of a resin jacket. Container (Patent Document 1), (2) Composite container for adhesive provided with a deformable notch for indirectly pressing an aluminum container to be accommodated with a finger on one side wall of a resin jacket (Patent Document 2) And (3) The composite container for adhesives (patent document 3) which provided the deformable press part for indirectly pressing the aluminum container to accommodate with a finger in the side wall of the resin outer container was proposed. (1) and (2) are more useful than the conventional composite containers for adhesives in that the amount of adhesive discharged can be adjusted and can be disposed of separately. In the case of (1), an aluminum container Since it is necessary to press directly with a finger, it may be damaged by a nail or the like, and it cannot be said that it is sufficient for precise adjustment of the discharge amount. In the case of (2), the precise adjustment of the discharge amount has been improved from (1), but when the viscosity of the adhesive is high, a part of the adhesive near the mouth of the aluminum container can be discharged. And tends to remain in the container. As for (3), it is possible to adjust the discharge amount of the adhesive as in (1) and (2), and it is possible to dispose of the waste. Further, the pressure is applied to the portion near the mouth of the aluminum container ( Since it is transmitted better than 1) and (2), it is useful in that the amount of adhesive remaining in the container is reduced. However, it is not satisfactory in terms of precise adjustment of the discharge amount of adhesive, and when the viscosity of the adhesive is high, the amount of adhesive remaining in the container tends to be relatively large. It was.

Other examples of the composite container for adhesive include design registration No. 1096733 and design registration No. 1096734, which have a structure in which an aluminum container is sandwiched between only two plate-like parts attached to respective pressing portions. Therefore, there is a disadvantage that the portion where the pressure is not transmitted well to the portion close to the tail of the aluminum container, and a part of the adhesive in the aluminum container cannot be discharged and remains in the container. . Therefore, it has been desired to develop a composite container for an adhesive in which the amount of adhesive remaining in the container that cannot be discharged from the aluminum container that contains the adhesive is reduced regardless of the viscosity of the adhesive.

Japanese Patent Laid-Open No. 2003-20078

JP 2003-226374 A

Japanese Patent Laid-Open No. 2004-1882249

The purpose of the present invention is to precisely adjust the discharge amount of the adhesive, and the amount of adhesive remaining in the container without being discharged from the aluminum container containing the adhesive is reduced regardless of the viscosity of the adhesive. It is to provide a composite container for an adhesive, and further to provide a composite container for an adhesive capable of precisely adjusting the discharge amount of the adhesive without directly touching an aluminum container containing the adhesive. .

  In order to solve the problems, the present inventors diligently studied an adhesive composite container having various shapes and mechanisms, and as a result, an aluminum container for containing an adhesive and window holes on both side walls were opened. There are two pressing parts provided with plate springs that are deformable for indirect pressing of the container made from the window holes provided in the side walls on both sides and are fixed at the upper end on the side in contact with the aluminum container. By using the composite container for an adhesive comprising the resin outer container for housing the aluminum container, the amount of the adhesive remaining in the container without being discharged from the aluminum container containing the adhesive is reduced. The present inventors have found that a composite container for adhesive can be obtained that can be reduced regardless of the viscosity of the adhesive and that can adjust the discharge amount of the adhesive more precisely.

In the composite container for adhesive of the present invention, the amount of adhesive remaining in the container without being discharged from the aluminum container containing the adhesive is reduced regardless of the viscosity of the adhesive, and the discharge amount of the adhesive is reduced. Can be adjusted more precisely.

  The composite container for adhesives of the present invention can be used for adhesives such as rubber adhesives, epoxy resin adhesives, urethane resin adhesives, silicone adhesives, and 2-cyanoacrylate adhesives. However, it is particularly suitable as a container for a 2-cyanoacrylate adhesive having a composition having a wide range of viscosity from low viscosity to gel.

  As an aspect of the composite container for adhesive according to the present invention, a window hole is formed in the aluminum container for housing the adhesive and both side walls, and the aluminum container is indirectly pressed from the window hole formed in the both side walls. A resin outer shell container for housing the aluminum container, and having two pressing portions each provided with a plate spring having an end fixed to the upper end on the side in contact with the aluminum container. As long as it is a composite container for adhesive, it may be symmetrical or asymmetrical, but the composite container as a whole is easy to carry out when holding by hand or pressing the pressing part delicately. It is preferable that it is a shape as shown in FIGS. 1-4 of this specification.

The plate spring in the present invention is used by molding a thermoplastic resin such as polypropylene, polyethylene, polyethylene terephthalate or the like, or a thermosetting resin such as polyurethane, into a deformable one.

In the present invention, when the ends of the plate springs are fixed to the upper ends of the two pressing portions on the side in contact with the aluminum container, the method is particularly limited as long as sufficient strength is obtained to press the aluminum container. Therefore, for example, only a part of one end may be fixed, or the entire part may be fixed. Similarly, the fixing method is not particularly limited as long as it is a method capable of obtaining sufficient strength to press the aluminum container. For example, the pressing portion and the plate spring are molded as one part. And a method of fusing or bonding the materials prepared as separate parts.

The width of the plate spring in the present invention is usually the same as the width of the tail portion of the aluminum container containing the adhesive or wider than the width of the tail portion. When it is narrower than the width of the tail of the aluminum container, the amount of the adhesive remaining in the container without being discharged from the aluminum container tends to increase.

The length of the plate spring in the present invention is usually prepared such that the end of the plate spring not fixed to the upper part of the tail of the aluminum container containing the adhesive is in contact with the end. Since the length after discharge of the aluminum container that contains the adhesive is shorter than before discharge, the position where the adhesive contacts is required to be a position where the tail is not pressed after discharge. Specifically, the position above the tail is preferably 1 to 30 when the length of the tail from the shoulder of the aluminum container in which the adhesive is accommodated is 100, and is only 10 to 20 above. The position is further preferred.

Further, two presses provided with plate springs that are deformable for indirect pressing of the aluminum container from the window holes formed on the side walls on both sides and are fixed to the upper end on the side in contact with the aluminum container. The height of the part protruding from the window hole formed on the both side walls of the part to the outside of the resin outer container may be the same or different, but the difference is more precise in terms of the adhesive discharge amount. This is preferable because it enables easy adjustment.

The pressing portion in the present invention is used by molding a thermoplastic resin such as polypropylene, polyethylene, polyethylene terephthalate or the like, or a thermosetting resin such as polyurethane, into a recoverable one.
In addition, soft resin, rubber or the like can be used for the purpose of reducing the pressure applied to the hand at the part directly touched by the hand.
