Description

Technical Field

[0001] This utility model relates to the field of toothpaste packaging technology, specifically to a toothpaste pump bottle. Background Technology

[0002] Tube-type toothpaste bottles require squeezing the tube before each use. After a period of use, it becomes more difficult to squeeze out the toothpaste, and the amount of toothpaste squeezed out each time also varies with the squeezing force. Due to these issues, modern toothpaste packaging is gradually adopting pump-type packaging.

[0003] Pump-type toothpaste bottles dispense toothpaste by pressing the pump head on top of the bottle. However, toothpaste bottles on the market often stop dispensing when the amount of solution in the bottle is low, resulting in a waste of resources as there is still solution left in the bottle.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-6 As shown, this utility model discloses a toothpaste pump bottle, which includes a lower bottle body 1 and an upper bottle body 2.

[0025] The top of the lower bottle body 1 is provided with a receiving groove 11, and the bottom surface of the lower bottle body 1 is flat, so that the toothpaste pump bottle can be placed stably on a table or other place.

[0026] The upper bottle body 2 has a receiving cavity 23 inside, and the bottom end of the upper bottle body 2 is located in the receiving groove 11.

[0027] Preferably, the bottom end of the receiving cavity 23 is arc-shaped, and a central groove 24 is formed by downward indentation at the center of the bottom end of the receiving cavity 23. It should be understood that since the central groove 24 is located at the center of the bottom end of the receiving cavity 23, the solution (such as toothpaste; of course, solid particles with small particle sizes can also be pumped out, depending on the construction of the pump head and pump tube) inside the receiving cavity 23 will spontaneously converge to the central groove 24. Combined with the pump head, by placing the bottom end of the pump tube connected to the pump head into the central groove 24, the pump head can smoothly pump out all the contents of the receiving cavity 23, so that the solution in the toothpaste pump bottle can be completely pumped out and used, avoiding waste of resources.

[0028] In this embodiment, the upper bottle body 2 includes a first bottle body 21 disposed within a receiving groove 11 and a second bottle body 22 disposed above the first bottle body 21. The first bottle body 21 has a first receiving cavity 231, and the second bottle body 22 has a second receiving cavity 232. The first receiving cavity 231 and the second receiving cavity 232 form a receiving cavity 23. The first receiving cavity 231 is arc-shaped, and the second receiving cavity 232 is frustoconical. The center of the bottom end of the first receiving cavity 231 is concave downward to form an arc-shaped central groove 24. It should be understood that the arc-shaped first receiving cavity 231 further concentrates the solution in the receiving cavity 23 at the bottom of the bottle body, thereby making it easier for the pump head to pump the solution out of the receiving cavity 23.

[0029] Preferably, the depth of the receiving groove 11 is greater than the height of the first bottle body 21. It should be understood that since the bottom end of the first bottle body 21 is a convex arc end, the upper bottle body 2 cannot be placed stably on a table or other surface alone. Therefore, the bottom of the upper bottle body 2 (i.e., the first bottle body 21) needs to be placed into the receiving groove 11 of the lower bottle body 1, and then the lower bottle body 1 can be placed on the table through its flat bottom surface.

[0030] Furthermore, the top end of the second bottle body 22 extends upward to provide a protrusion 25, the protrusion 25 having a receiving hole 251 communicating with the second receiving cavity 232, and the outer wall of the protrusion 25 having an external thread 252. It should be understood that the pump head used to pump out the solution in the upper bottle body 2 can be threaded to the top end of the second bottle body 22 through the external thread 252 of the protrusion 25 (that is, the pump head has an internal thread corresponding to the external thread 252).

[0031] Preferably, the first bottle body 21, the second bottle body 22, and the protrusion 25 are integrally formed.

[0032] In this embodiment, the connection between the first bottle body 21 and the second bottle body 22 is connected to the inner wall of the receiving groove 11 via a snap-fit ​​structure. That is, the upper bottle body 2 and the lower bottle body 1 are detachably connected. After the solution in the upper bottle body 2 is used up, it is only necessary to replace the upper bottle body 2 containing the pumpable substance and re-insert it into the lower bottle body 1 for reuse (the lower bottle body 1 is reusable). This makes the replacement cost of the toothpaste pump bottle relatively low.

[0033] Alternatively, the connection between the first bottle body 21 and the second bottle body 22 is connected to the inner wall of the receiving groove 11 by a threaded connection.

[0034] Preferably, the cross-section of the connection between the first bottle body 21 and the second bottle body 22 is circular, wherein the outer diameter of the connection between the first bottle body 21 and the second bottle body 22 is equal to the diameter of the receiving groove 11.

[0035] Furthermore, one of the outer wall at the connection between the first bottle body 21 and the second bottle body 22 and the inner wall at the top of the receiving groove 11 is provided with a ring-shaped receiving slot 26, and the other of the outer wall at the connection between the first bottle body 21 and the second bottle body 22 and the inner wall at the top of the receiving groove 11 is provided with a ring-shaped protruding retaining ring 111 that is fitted into the receiving slot 26.

[0036] like Figure 3 and Figure 5 As shown, the outer wall of the connection between the first bottle body 21 and the second bottle body 22 in this application is provided with a receiving slot 26, and the inner wall of the top of the receiving groove 11 of the lower bottle body 1 is provided with a protruding retaining ring 111 corresponding to the receiving slot 26, and the protruding retaining ring 111 is engaged in the receiving slot 26 (e.g., Figure 6 As shown in the figure, this allows the bottom of the upper bottle 2 to be installed in the receiving groove 11 of the lower bottle 1.

[0037] Preferably, the connection between the first bottle body 21 and the second bottle body 22 of the upper bottle body 2 can be made of a soft material, so that the bottom of the upper bottle body 2 can be installed more smoothly in the lower bottle body 1. Alternatively, the receiving slot 26 is coated with a magnetic material layer, and the raised retaining ring 111 is made of a magnet, which is attracted to the magnetic material layer.

[0038] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
