Description

The present invention relates to a solid paste container, and more particularly to a solid paste container improved so that a cap can be easily removed from a container body.

  Conventionally, for example, as shown in Japanese Patent Publication No. 8-5502, a container body is filled with glue and solidified into a rod shape, and a tail plug (knob) attached to the bottom of the container body is operated to open the front end of the container body. There is provided a solid paste to be used in and out of the section. When not in use, cover the tip of the main body to prevent the glue from drying.

Japanese Patent Publication No.8-5502

  By the way, in such a type of paste container, as described in Japanese Patent Application, the container body and the cap extend in the circumferential direction on the outer periphery and the cap on the inner periphery in the circumferential direction. Ring-shaped ridges having low lengths are respectively formed, and when the cap is put on the main body, the ridges get over each other to prevent the cap from coming off.

  Although not specifically described in Japanese Patent Publication No. 8-5502, an air tight portion is formed at a position closer to the distal end side as viewed from the main body side than the locking portion constituted by the protruding ring. It is common. In other words, since the airtightness between the main body and the cap cannot be secured at the locking portion, the fitting portion tightly fits on the outer periphery of the main body and the inner periphery of the cap separately and has a high degree of sealing performance. The joint part is formed as an air tight part. Therefore, it is relatively easy to push the head of the cap when attaching the cap to the main body. However, it is not easy to remove the cap from the main body, and an extremely strong force is required.

  Furthermore, when this glue is used, the glue protruding from the main body is rubbed against the paper surface. As a result, a part of the glue protrudes from the opening of the container body to the side, and the outer periphery of the main body and the cap are covered. May be drawn between the inner periphery of the two and may adhere to each other. In this case, a stronger force is required to remove the cap.

  This invention is made | formed in view of the said conventional problem, and makes it the subject to provide the container for solid glue which can remove a cap easily.

  In order to solve the above-mentioned problems, the present invention provides a solid paste container comprising a cylindrical container body having an open upper end and a cap attached to the opening side. The cap has an upper end closed and a lower end opened. A cylindrical cap main body, a ring portion disposed below the cap main body, and a connection portion for connecting the cap main body and the ring portion. A plurality of connecting portions are provided at predetermined intervals in the circumferential direction of the cap, extend in the axial direction of the cap, and are integrally connected to the cap main body and the ring portion at both ends so as to be deformable. The container body includes a ring portion receiving portion that receives the ring portion and prevents further downward movement with respect to the container body, and when the cap is put on the container body in a predetermined state, the connecting portion of the cap Is deformed radially outward of the container.

  In the solid glue container according to the present invention having the above-described configuration, when the cap is put on the container body in a predetermined state, the connecting portion is deformed into a state in which the container swells radially outward. When removing the cap, if the connection portion is grasped by hand, the ring portion cannot move downward, so that the cap body moves upward and the cap can be easily removed.

  Embodiments of the present invention will be described below with reference to the drawings. 1 is a front view showing a solid paste container 1 according to a first embodiment of the present invention, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, FIG. 3 is a front view of a cap, and FIG. It is a BB line sectional view, and in the figure, numerals 2 are container main parts and numerals 21 are caps.

  The container main body 2 includes a large-diameter portion 3 having a large outer diameter on the lower side and a small-diameter portion 4 having a small outer diameter connected to the large-diameter portion 3 via a shoulder portion 5 extending in the radial direction. The tip of the portion 4, that is, the upper end of the container body 2 is open. At a position away from the upper end of the small-diameter portion 4 by a predetermined distance in the axial direction, a low-length rib or ridge 6 extending in the circumferential direction, that is, a linearly extending protrusion, is formed on the entire outer periphery thereof. . This will be described later. Reference symbol P denotes a paste filled in the container body 2, and the paste P is inserted into and removed from the container body 2 by a tail plug 15 attached to the lower portion of the container body 2 (described in the aforementioned Japanese Patent Publication No. 8-5502). This mechanism is known by Japanese Patent Publication No. 8-5502 and has no direct relationship with the present invention, and the description thereof is omitted.

  The cap 21 is made of a plastic such as PP, and includes a cap body 22, a ring portion 30, and a connection portion 31 that are integrally formed. The cap main body 22 is a cylindrical portion whose upper side is closed, and includes a main body upper portion 23 having a small inner diameter on the upper side and a main body lower portion 25 having a large inner diameter connected to the main body upper portion 23 via a shoulder portion 24 extending in the radial direction. ing. On the inner periphery of the main body lower portion 25, two low-length ribs or ridges 26, 27, that is, linearly extending projections extending in the circumferential direction with a predetermined distance in the axial direction are formed over the entire circumference. Has been. These will be described later.

  Reference numeral 30 denotes a ring portion formed in a short annular shape. The ring portion 30 is disposed concentrically below the cap body 22 and is connected to the cap body 22 by a connection portion 31. That is, a plurality of connecting portions 31 are formed at predetermined intervals in the circumferential direction of the cap (in this embodiment, four at 90 ° intervals), and have a width extending in the circumferential direction of the cap and a length extending in the axial direction. It has a generally plate shape, and is integrally connected to the cap body 22 and the ring portion 30 at both ends in the length direction. In the present embodiment, in the present embodiment, a substantially V-shaped cut or groove 32, 33, 34 is formed on the outer peripheral surface side of the connection portion at the connection portion at both ends and in the longitudinal direction. As a result, hinge portions 35, 36, 37 called so-called PP hinges are formed, and these hinge portions 35, 36, 37 are bent.

  As shown in FIGS. 3 and 4, the connection portion 31 of the cap 21 does not bend at the hinge portions 35, 36, and 37 and hangs straight down, as shown in FIGS. 3 and 4. When the cap 21 is put on the container body 2, the hinge portions 35, 36, and 37 are bent as shown in the figure. Details will be described below.

  As shown in FIGS. 1 and 2, in the state where the cap 21 is put on the container body 2, first, the protrusion 27 on the lower side of the cap body 22 gets over the protrusion 6 formed on the small diameter portion 4 of the container body 2. The cap 21 is positioned so as to prevent the cap 21 from coming off. In this state, the upper protrusion 26 which is the air tight portion of the cap body 22 is fitted into the air tight portion 7 of the container body, and the space between the container body 2 and the cap body 22 is hermetically sealed in this portion. . Further, the shoulder portion 24 of the cap main body 22 hits the upper end surface 8 of the small diameter portion 4 of the container main body 2, thereby preventing further movement of the cap main body 22.

  On the other hand, the lower surface side of the ring portion 30 of the cap 21 abuts on the shoulder portion 5 between the large diameter portion 3 and the small diameter portion 4 of the container main body 2, and the connection portion 31 is bent as shown in the figure. That is, the distance from the shoulder portion 24 of the cap body 22 of the cap 21 to the lower surface of the ring portion 30 is longer than the distance from the upper end surface 8 of the small-diameter portion 4 of the container body 2 to the shoulder portion 5. When the container body 2 is covered and moved downward, the ring portion 30 of the cap 21 comes into contact with the shoulder 5 of the container body 2 first, and when the cap body 22 is further moved downward, the cap body 22 side is prevented from coming off. The protruding ridges 27 get over the protruding ridges 6 on the container body 2 side and engage in a retaining state. (However, this engagement state can be overcome, and this engagement is released if a force is applied to the cap body 22 and moved upward.) On the other hand, another protrusion 26 of the cap body 22 is removed from the container body. 2 fits in the air tight part 7. At approximately the same time, the shoulder 24 of the cap body 22 abuts on the upper end surface 8 of the container body 2. Meanwhile, the connecting portion 31 is bent at the hinge portions 35, 36, and 37 as shown in the figure. The inner diameter of the ring portion 30 and the connection portion 31 of the cap 21 is slightly larger than the outer diameter of the small diameter portion of the container main body 2, and the cap 21 is smoothly attached to the container main body 2.

  In order to remove the cap 21 from the container main body 2, the connecting portion 31 of the cap 21 may be grasped by hand in the state shown in FIGS. By grasping, the connecting portion 31 that has been curved outward in the radial direction is pushed inward to return from the curved state to the straight state shown in FIGS. At this time, since the lower ring portion 30 is in contact with the shoulder portion 5 of the container main body 2 and cannot move downward, the cap main body 22 is pushed upward by the connection portion 31 that tries to extend straight. Accordingly, as described above, the engagement between the protrusion 27 on the cap body 22 side and the protrusion 6 of the container body 2 is overcome, and the protrusion 27 covers the protrusion 26 and the cap 21. The cap is removed from the opposite side, and the other protrusion of the cap body 22 is detached from the air tight portion 7 of the container body 2. In this state, the cap 21 can be easily removed from the container body 2. As described above, in the present embodiment, the cap for holding the cap is not held by grasping the connecting portion by hand, instead of holding the cap by hand and pulling to remove the cap and removing the fitting of the air tight portion. And the tight fitting at the air tight part is removed, so that the cap can be removed very easily. In addition, when the connecting portion is formed so as to be bent slightly outward in the radial direction in the free state, the outward deformation of the connecting portion when the cap is attached to the container body becomes smooth.

  FIG. 5 is a longitudinal sectional view showing a cap 51 used in the second embodiment, and corresponds to FIG. 4 according to the first embodiment. The basic configuration of the cap 51 in this embodiment is the same as that of the cap 21 according to the first embodiment, but the hinge portion is also provided differently. That is, the cap 51 also includes a cap main body portion 52, a ring portion 60, and a connection portion 61. The cap main body 52 includes a main body upper portion 53 having a small inner diameter, and a main body lower portion 55 having a large inner diameter connected thereto via a shoulder portion 54. On the inner periphery of the main body lower portion 55, an air tight protrusion 56 and a retaining ring are provided. The protruding ridges 57 are provided in the same manner as in the first embodiment. The shape of the ring part 60 is the same as that of the first embodiment.

  Similarly to the first embodiment, the connecting portions 61 are provided at four positions at intervals of 90 degrees in the circumferential direction, and are formed in a plate shape having substantially the same width and length as that of the first embodiment. Yes. Then, a substantially V-shaped groove or notch 62, 63 is formed in the connecting portion between the connecting portion 61 and the cap main body 52 and the ring portion 60, thereby forming hinge portions 64, 65. These hinge portions 64, 65 are formed. Can be bent. In this embodiment, unlike the first embodiment, no hinge portion is formed at the intermediate portion in the longitudinal direction of the connecting portion 61. Therefore, in this embodiment, when the cap 51 is attached to the container body, the connecting portion 61 bends outward in an arc shape. The wall thickness of the connecting portion 61 is set so as not to hinder the bending and to obtain sufficient strength. In addition, as described in relation to the first embodiment, the connecting portion may be molded so as to be bent slightly outward in a free state.

  FIG. 6 is a longitudinal sectional view of a cap 71 used in the third embodiment. The cap 71 also includes a cap main body 72, a ring portion 73, and a connection portion 74. As shown in the figure, unlike the first and second embodiments, no groove is formed in the connection portion between the connection portion 73 and the cap body 72 and the ring portion 73. However, the connecting portion 73 is thinner than the first and second embodiments, and is easily bent. Further, the connecting portion may be shaped to be bent slightly outward in the free state so that the outward bending is surely and smoothly generated in the initial stage of deformation.
