Description

  TECHNICAL FIELD The present invention relates to a container with a dispenser, and in particular, a container (for example, a bag) whose storage space is narrowed (hereinafter simply referred to as volume reduction) in accordance with the occurrence of liquid leakage due to poor screwing of the dispenser or the reduction in contents. In the case of applying a thin-walled container), it is intended to surely prevent the discharge failure caused by the ingress of air, which has been a concern in the past.

For relatively compact containers filled with facial cleansers, hair styling agents, emulsions, etc., a container equipped with a dispenser is often used to facilitate the proper discharge of the contents. The main body part is placed inside the decorative cover and directly connected to the dispenser. After the contents have been used up, only the main body part is replaced and the dispenser and decorative cover are reused as they are. As a result, the amount of materials used for merchandise is reduced to effectively use resources (see, for example, Patent Document 1).
JP 2002-362632 A

  By the way, this type of container is usually attached to the container body by screwing the dispenser or the like, and the contents are sucked through a dip tube connected at the lower part of the dispenser to discharge the contents from the nozzle head. The negative pressure in the container that occurs when the contents are discharged (the negative pressure that accompanies the weight loss of the contents) is released by taking the reduced amount of the outside air into the container. Either prevent the container from being deformed, or reduce the volume of the main body according to the weight loss of the contents, or slide the inner tray to reduce the volume of the main body according to the weight loss of the contents. It was normal.

  However, if the dispenser is not screwed in sufficiently and the container body and the dispenser are not securely connected to each other, the seal between the dispenser and the mouth of the container will be incomplete, and the contents will leak out from the site. There was a bug. In particular, in a container with a mechanism that reduces the volume of the main body according to the weight reduction of the contents, or reduces the volume of the main body by sliding the inner tray according to the weight reduction of the contents, air is introduced into the main body of the container. It has often been found that the contents cannot be discharged even if the dispenser is operated and the so-called air biting occurs, and there is still room for improvement in this respect.

  The subject of this invention exists in the place which proposes the container with a novel dispenser which can grasp | ascertain visually whether the dispenser was reliably mounted to the main-body part of the container.

According to the present invention, a main body portion for storing contents and a mouth portion of the main body portion are screwed via a base cap, and the contents of the main body portion are sucked, pressurized and compressed by a pressing operation of the head, and ejected to the outside. A container with a dispenser,
The shoulder portion of the main body portion is provided with a wall portion that stands up to face the mouth portion of the main body portion,
The base cap is provided with a peripheral wall that forms a groove portion opened downward in cooperation with the outer wall of the base cap and is movable along the outer surface of the wall portion by rotation of the base cap.
On the outer surface of the wall portion, an indicator that displays the degree of screwing of the base cap according to the movement of the peripheral wall is formed,
The container with a dispenser is characterized in that an elastic member for forcibly pushing out the wall portion that has entered the groove portion by its own repulsive force is provided at the protruding end of the wall portion.

  In the container with a dispenser having the above-described configuration, the main body portion is configured as an inner container that enables volume reduction of the storage space in accordance with a reduction in the contents, and a decorative cover disposed outside the inner container. can do.

  The groove may be provided with a rib that directly contacts the elastic member to increase the repulsive force of the elastic member, and at least one of the side wall of the groove and the wall facing the side wall. In addition, it is possible to form a narrow groove for discharging the air present in the groove.

  The screwed state of the base cap is reflected on the wall, so that when the container manufacturing process (assembly process) or the consumer refills the contents, it is visually confirmed whether the dispenser is securely attached to the container body. It is possible to prevent the leakage of the contents due to the seal failure and the discharge failure of the contents due to the air bite.

  Further, when the dispenser is removed, the wall forming the index is forcibly pushed out of the groove due to the presence of the elastic member, so that the screwed state when the dispenser is remounted by the index can be repeatedly confirmed.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
1 and 2 show an embodiment of a container with a dispenser according to the present invention.
In the figure, reference numeral 1 denotes a main body portion for storing contents. This main body part 1 is a thin-walled (torso, thin-walled bottom) inner container (thin blow-molded container, tube, pouch, etc.) 1a that enables the volume of the storage space M to be reduced according to the weight reduction of the contents, and this inner container 1a The cover 1b is composed of a cylindrical body having an upper end opening 1b ₁ and a lower end opening 1b _2, and inside the shoulder portion of the inner container 1a. A vertical groove 1b ₃ is provided in association with the vertical rib r provided on the cover 1 to hold the cover 1b in a non-rotatable manner (the vertical rib may be provided in the cover 1b and the vertical groove may be provided in the inner container 1a). .

The cover 1b may be configured as a container body (including a structure that can be divided at the middle of the body) without forming the lower end opening 1b _{2 or} by laminating the main body portion 1. You may comprise as a lamination | stacking exfoliation type container from which an inner layer peels with the structure and weight reduction of the content.

  2 is a dispenser. The dispenser 2 is composed of a peripheral wall and a top wall, and a base cap 2a that is screwed on the peripheral wall outside the mouth of the inner container 1a, a pump mechanism 2b that is suspended from the lower surface of the base cap 2a, and a pump mechanism It comprises a head (nozzle head) 2c that operates 2b to suck, pressurize and compress the contents in the inner container 1a.

Further, 3 is a peripheral wall that integrally rises from the edge of the top wall of the base cap 2a and surrounds the lower part of the head 2c (used as a grip when attaching a dispenser), and 4 is the end of the upper end opening 1b ₁ of the cover 1b. It is an annular wall portion that stands up at the edge adjacent to the mouth portion of the inner container 1a (a plurality of block-like ones may be arranged at intervals). This wall portion 4 is made of a separate object from the cover 1b, and an indicator (characters, symbols, decorations such as printing, hot stamping, vapor deposition, etc.) for displaying the screwing degree of the base cap 2a on the outer surface thereof. Color or the like or material color)) is formed.

  In the case where the index is displayed in color or material color, the visual recognition is further ensured by using a color or material color different from that of the cover 1b or the base cap 2a.

  Reference numeral 5 denotes a peripheral wall provided on the outer peripheral wall of the base cap 2a. The peripheral wall 5 forms a groove S that is opened downward in cooperation with the outer peripheral wall of the base cap 2a. The peripheral wall 5 is moved along the outer surface of the wall 4 by turning (screwing) the base cap 2a. It can be moved.

  Further, 6 is an elastic member that is disposed at the protruding end (upper end) of the wall portion 4 and forcibly pushes out the wall portion 4 that has entered the groove portion S with its own repulsive force. The elastic member 6 can be formed of a member such as rubber or elastomer, and a slit 6a that forms a space for absorbing deformation in the groove S is formed at the tip thereof. The elastic member 6 is advantageously adapted to be integrated with the wall portion 4 by insert molding.

  Whether or not the base cap 2a is securely screwed depends largely on the sense of the person performing the work, and in the case of the conventional structure where the connection (screwing etc.) with the body part 1 of the dispenser 2 is insufficient Leakage of contents and air biting due to poor sealing may occur, but in the container according to the present invention, the wall 4 is inserted into the groove S by screwing the base cap 2a, and the tip of the peripheral wall 5 To match the index on the wall 4 (a mark or the like indicating when the tip of the mouth of the inner container 1a comes into contact with the packing P to be in a sealed state) or move the index until it is covered. It is possible to visually confirm that the connection between the main body portion 1 and the main body portion 1 is secure, and there is no discharge failure due to liquid leakage or air biting.

  When inserting the wall part 4 into the groove part S, a gap is formed between the female base cap 2a and the wall part 4 or between the wall part 4 and the peripheral wall 5 in order to discharge air existing in the groove part S. Thus, the wall thickness or groove width of the wall portion 4 is set, or the air discharge narrow groove 7 (which may be a rib) is provided in any of the base cap 2a, the wall portion 4 and the peripheral wall 5.

  In FIGS. 1 and 2, the base cap 2a is completely attached with the wall 4 fully inserted into the groove S, and the screwed state is confirmed by a change in color or the like by covering the index in the same state. For example, as shown in FIG. 3, a line L is attached to the outer surface of the wall 4 in addition to the index, and the screwing is completed when the lower end of the peripheral wall 5 reaches the line L. Can also be displayed. Although not shown, the notch or through hole is provided in the peripheral wall 5, and the indicator 2 indicates the mounting state of the dispenser 2 by matching the notch or through hole with the indicator provided on the outer surface of the wall part 4, etc. In addition to the above, it may be possible to double check by adding additional information.

  In the case where refilling or the like is necessary from the connection completion state of the dispenser 2 with the main body part 1, the connection state between the dispenser 2 and the main body part 1 will be released. The external force applied to the elastic member 6 that has been compressed and deformed so as to fill the slit 6a in order to absorb the deformation is released, and the elastic member 6 returns to its original shape by the pushing force (repulsive force). This makes it possible to visually recognize the indicator from the outside, and when the dispenser 2 is remounted on the main body part 1, the wall 4 is again inserted into the groove S by screwing the base cap 2a, and the peripheral wall 5 Just move the tip of the dispenser 2 until it matches the indicator on the wall 4 (a mark indicating when the tip of the mouth of the inner container 1a comes into contact with the packing P and becomes sealed) or covers the indicator 2 It is possible to visually grasp that the connection between the main body portion 1 and the main body portion 1 is ensured.

4 (a) to 4 (e) show modified examples of the elastic member 6. FIG.
In order to make it easier to absorb the deformation in the groove S, the elastic member 6 can be a bellows type as shown in FIG. In addition, the elastic member 6 is provided with V-shaped concave portions at a plurality of locations as shown in FIG. 4 (b) to absorb deformations, or as shown in FIGS. 4 (c) and (d). A horizontal slit may be provided inward or outward to absorb the deformation at the site, and as shown in Fig. 4 (e), a triangular cross-sectional shape tapering toward the tip is formed on both sides. An absorption region for deformation may be formed, and in any case, the elastic member 6 can be annular like the wall portion 4, and the shape thereof is appropriately changed according to the wall portion 4.

  In order to further enhance the pushing force (repulsive force) of the elastic member 8, the groove portion S may be provided with a plurality of vertical ribs 8 as shown in FIG.

  As an embodiment of the present invention, a bag-like inner container 1a is arranged inside the cover 1b, but the outside air corresponding to the weight loss of the contents is taken into the container and the container is deformed by negative pressure or the like. It is also possible to apply to containers with a dispenser of the type that prevents spillage and containers that are designed to reduce the volume of storage space by sliding the container's inner tray upward in accordance with the weight loss of the contents. Not.

  Further, in each of the above embodiments, for example, it is possible to adopt a configuration in which the peripheral wall 3 is omitted, and the parts configuration, shape, and the like can be appropriately changed without departing from the gist of the present invention.

  It is possible to visually check whether the dispenser is securely attached to the main body of the container during the container manufacturing process or when the contents are refilled by the consumer. Content leakage due to poor sealing due to insufficient screwing And a dispenser-equipped container that does not cause discharge failure due to air biting.

  Further, since the wall forming the index is forcibly pushed out of the groove due to the presence of the elastic member when the dispenser is removed, confirmation of the screwed state when the dispenser is remounted by the index can be repeatedly performed.

It is the figure which showed embodiment of the container with a dispenser according to this invention. FIG. 2 is a diagram showing a state where a dispenser is completely attached in the container shown in FIG. It is the figure which showed the front of the wall part.
