Description

  The present invention relates to a refill pack holder in which a refill pack filled with liquid is accommodated and a liquid jet pump is attached to a holder opening.

  As liquid products such as shampoos, rinses, and detergents, products sold by being filled in a hard bottle-like container equipped with a liquid jet pump are well known. This is an easy-to-use device that can inject the internal solution by grasping or pushing the liquid jet pump. However, every time the content liquid such as detergent is used up, it has become a problem to discard the bottle-like container with the liquid jet pump. More specifically, it became a problem from the viewpoint of energy saving and environmental destruction.

  Therefore, in order to reduce the waste as much as possible, it is also carried out by filling the content liquid such as a detergent in a soft bag-like refill pack. In this case, after purchasing the detergent etc. in the refill pack, the content liquid is transferred from the refill pack to an empty bottle-shaped container, and a liquid jet pump is attached to the bottle-shaped container. become. On the other hand, the bottle-shaped container can be used again, contributing to the reduction of waste.

  By the way, the applicant of the present application invented a refill pack holder that can accommodate the refill pack as it is to simplify the trouble of transferring the solution in the soft bag-like refill pack to the hard bottle-like container. And is known (Patent Document 1).

This refill pack holder is provided so that the front half and the rear half that cover the front side and the rear side of the refill pack can be opened and closed, and the fastening means for holding the closed state for the front half and the latter half is provided on the left and right sides of the front half and the latter half. It is provided at the end.
In addition, as a bottle container-shaped part formed by the closed state of the front half and the latter half, in order from top to bottom, a mouth part for attaching the liquid jet pump and a shoulder part for sandwiching the upper part of the refill pack from the front and rear And the trunk | drum which covers the circumference | surroundings of the refill pack, and the bottom part which mounts a refill pack is provided.

In addition, a single rib and a ditch that hold the top of the refill pack are extended in the front and rear halves along the abutment surface from the mouth to the shoulder. The surface is in a horizontal straight line when viewed in plan. When the refill pack is accommodated in this refill pack holder, the upper side of the refill pack is exposed above the shoulder, so the liquid jet pump is usually fixed to the mouth after cutting off that part. I was using it.
When this use state is viewed in plan, the upper cut end of the refill pack is sandwiched and sealed from the front and the rear in a state of being in a horizontal straight line. By this clamping, even when the refill pack holder falls down, the content liquid does not leak from the upper cut end of the refill pack accommodated therein.

JP 2007-15767 A

  However, in the form in which the upper portion of the refill pack is sandwiched in a horizontal line at the shoulder, the width of the refill pack holder inevitably becomes wider than the upper portion of the refill pack when viewed from the front. Moreover, since the shoulder portion is provided with the fastening means outside the portion sandwiching the upper part of the refill pack, the width of the refill pack holder is further increased by the amount of the fastening means.

  In addition, the refill pack usually has an elliptical bottom surface and a flat shape with two upper and lower sheets attached to the front and back. It has a form. In order to accommodate such a wide refill pack, the refill pack holder has a wider shape. Therefore, for example, when a plurality of refill pack holders are arranged in a horizontal row, the installation space has a corresponding width.

  In addition, since the two sheets before and after the refill pack only overlap in a horizontal line, in this holding form, the force that prevents liquid leakage from the refill pack itself (the force that the two sheets overlap in the front and back) is: Not created. Therefore, it has been necessary to provide a single rib and a groove between the two sheets over the entire length in the width direction of the shoulder. In addition, the fastening force of the fastening means that is the basis of the fitting force between the single rib and the recessed groove has to be strengthened, making product design difficult.

  The present invention was created in view of the above circumstances, and its purpose is to provide a refill pack holder capable of at least narrowing the lateral width on the assumption that there is an effect of preventing liquid leakage. is there.

  The present invention provides a front body that covers the front side of the refill pack and a rear body that covers the rear side so as to be openable and closable, and the front body and the rear body form a container shape in a butted closed state, and from top to bottom. In order, a holder mouth portion for mounting the liquid jet pump, a holder shoulder portion that sandwiches the top of the refill pack from the front and back, a holder body portion that covers the periphery of the refill pack, and a holder bottom portion on which the refill pack is placed, And the holder mouth portion is formed into a cylindrical shape by abutting the front mouth portion of the front body and the rear mouth portion of the rear body, and the holder shoulder portion, It consists of a front shoulder part of the front body and a rear shoulder part of the rear body. The front shoulder part and the rear shoulder part are provided with a front clamping part on the front side of the abutting part and a rear clamping part on the rear side. A pack holding part is formed by holding the upper part of the refill pack by the holding part. , Characterized in that curved when viewed in plan.

  It does not matter how the pack clamping portion is curved in plan view. Further, it does not matter where the holder mouth portion is in the pack holding portion. However, in order to further reduce the width of the refill pack holder, it is desirable to do the following. That is, as in the second aspect of the invention, the pack sandwiching portion is curved in a U shape that swells in an arc shape toward the front side when viewed in plan, and the holder mouth portion is curved in a U shape in plan view. It is located in the intermediate part of a clamping part.

  When viewed from above, the shape of the holder shoulder and the holder body is not limited, but in order to make the shape using the U-shape of the pack clamping portion, it is desirable to do as follows. That is, as in the third aspect of the invention, the holder body is composed of a front body of the front body and a rear body of the rear body, and the holder shoulder is formed on the outer peripheral side of the pack holding part. The concealing part is composed of a front concealing part of the front shoulder part and a rear concealing part of the rear shoulder part, and the front side of the front concealing part is from a U-shaped pack sandwiching part in plan view. An arc shape that swells to the front side, and a rear side of the rear concealing portion is a straight shape that covers the rear side of the pack holding portion.

  It does not matter whether the front body and the rear body are separate molded products or integrally molded products. Any material can be used as long as it can hold the refill pack. Further, the position where the lock portion is provided is not limited. The position where the function of the lock part can be exhibited most efficiently is the left and right ends of the holder shoulder, but the holder shoulder has a unique role of sandwiching the upper part of the refill pack from the front and the back. is there. Therefore, if the lock portion is provided on the holder shoulder while fulfilling this unique role, the lateral width of the holder shoulder is likely to be widened, and consequently, the lateral width of the refill pack holder is widened. In order to make the function of the lock part sufficiently exhibited while suppressing the width of the refill pack holder and to easily open and close the front and rear bodies, it is desirable to do the following. That is, as in the invention of claim 4, the front body and the rear body are continuous by a deformable connecting piece provided on the bottom of the holder, and are an integrally molded product made of synthetic resin, A lock portion is provided.

  The opposing surfaces of the front clamping part and the rear clamping part may be flat surfaces without irregularities, but in order to exhibit the function of sealing the upper part of the refill pack, it is desirable to do the following. That is, as in the invention of claim 5, the convex rib portion is provided on one side of the opposing surfaces of the front clamping portion and the rear clamping portion, and the concave groove portion that meshes with the convex rib portion is provided on the other side.

It seems that it is essential to form the convex rib portion and the concave groove portion that seal the upper portion of the refill pack over the entire length of the holder shoulder portion due to the nature of sealing. In addition, since the length of the convex rib portion and the concave groove portion corresponds to the length of the refill pack sandwiched between the convex rib portion and the concave groove portion, the longer the lock portion, for example, the male portion and the female portion. A large force is required to fit the two. However, if the upper cut end of the refill pack can be sufficiently sealed, the shorter the formation length of the convex rib portion and the concave groove portion, the easier to operate the lock portion.
Further, when the upper part of the refill pack is curved in a U shape, the two sheets of the refill pack naturally overlap each other by the restoring force. This overlapping state seems to be particularly strong in the vertically extending portions of the left and right sides of the U-shape. This is because the U-shaped vertically extending portions on both the left and right sides are the portions where the restoring force acts most. Therefore, a sufficient sealing effect can be obtained without providing convex ribs and grooves in the longitudinally extending portion. That is, as in the invention of claim 6, the U-shaped butting surface of the pack sandwiching portion includes a central laterally extending portion extending along the left-right direction, and a left-right longitudinally extending portion extending along the front-rear direction. The laterally extending portion and the left and right longitudinally extending portions are composed of a circular arc portion, and the convex rib portion and the concave groove portion are formed only in the laterally extending portion and the circular arc portion.

According to the first aspect of the present invention, in the holder shoulder portion, the pack holding portions provided before and after the abutting surfaces of the front shoulder portion and the rear shoulder portion are curved in plan view. The top of the replacement pack is also naturally curved. As a result, the width of the refill pack is reduced by the amount of curving when viewed from the front, compared to the conventional case in which the upper part of the refill pack is held in a straight line. The width can be narrowed. Therefore, even when several refill pack holders are juxtaposed, the installation space can be reduced.
In addition, since the upper part of the refill pack is not only sandwiched by the pack holding part, but also curved, the two sheets before and after the refill pack are firmly overlapped, and liquid leakage from the upper part It becomes difficult to do.

  According to the second aspect of the present invention, since the pack holding portion is curved in a U shape in plan view, the lateral width of the refill pack holder can be further reduced. In addition, since the holder opening is located at the intermediate portion of the pack holding portion, the refill pack is uniformly held on both the left and right sides of the pack holding portion, and the liquid does not leak easily.

  According to the invention of claim 3, by taking advantage of the shape of the pack holding portion that is curved in a U-shape, the holder shoulder portion is provided with a concealing portion that continues to the holder body portion on the outer peripheral side of the pack holding portion. And since the front side of the front concealment part has an arc shape that swells to the front side from the U-shaped pack holding part, and the rear side of the rear concealment part is a straight line that closes the rear side of the pack holding part, the left and right lateral width is narrowed In addition, it can be said that it is excellent in aesthetics that skillfully utilizes the shape of the pack clamping portion.

  Since the lock part is provided in the holder trunk | drum, the width | variety of the refill pack holder can be suppressed compared with the case where it provides in the holder shoulder part. In addition, the holder shoulder portion can sufficiently exhibit the sealing role of holding the refill pack.

  The invention of claim 5 is provided with a convex rib portion on one side of the opposed surfaces of the front clamping portion and the rear clamping portion, and a concave groove portion that meshes with the convex rib portion on the other side, so that the upper portion of the refill pack is sealed The function to do can be demonstrated further.

  In the invention of claim 6, the convex rib portion and the concave groove portion are formed only in the laterally extending portion of the central portion of the U-shaped butting surface of the pack sandwiching portion and the circular arc portion continuous to the lateral portion. Since the two sheets of the refill pack naturally overlap each other at the left and right side portions of the U-shape where the force acts, the sealing effect of the refill pack is sufficiently exhibited. Therefore, the formation length of the convex rib part and the concave groove part can be made shorter than the case where it is provided over the entire length of the holder shoulder part, and the lock part can be fitted with a correspondingly weak force. That is, it contributes to the improvement of the fitting work.
